Professional watercolor tube sets are the upgrade serious artists make when student-grade paint starts to feel chalky, dull, or limiting. I switched my own studio to tubes about three years ago, and the difference in pigment load, rewet behavior, and single-pigment color mixing was immediate. These are artist-grade watercolors with concentrated pigment, lightfast binders (gum arabic or honey), and squeezable tubes that let you control paint-to-water ratio in ways a pan set simply cannot.
After testing ten professional watercolor tube sets over the past several months, I can tell you exactly which brands deliver the vibrancy, transparency, and lightfastness working artists expect. The short answer for those in a hurry: Winsor and Newton Professional, Daniel Smith, Schmincke Horadam, Holbein Artists, and Sennelier are the most trusted professional watercolor brands, with M. Graham, MaimeriBlu, QoR, ShinHan, and Rembrandt filling out the tier. Below I break down each set, what it does best, and where it falls short.
I focused this guide exclusively on tubes (since the topic specifies tubes), and I weighted lightfastness, pigment load, single-pigment count, color range, and real-world mixing performance. Every recommendation here is one I have either tested myself or watched multiple professional watercolorists use in studio and plein air settings.

1. Daniel Smith Essentials Introductory Set – Split-Primary Starter
DANIEL SMITH 285610005 Extra Fine Essentials Introductory Watercolor, 6 Tubes, 5ml, Blue/Transparent/Yellow, 0.17 Fl Oz (Pack of 6)
6 tubes, 5ml
Split-primary colors
Lightfast AA
Rewettable, transparent
Pros
- Highly pigmented colors that go a long way
- Excellent color mixing range from just 6 colors
- Rewets easily with vibrant transparent washes
- Smooth consistency for effortless application
- Split-primary system covers the full color wheel
Cons
- French Ultramarine granulates unpredictably
- A few colors are mixed-pigment rather than single pigment
- 5ml tube size feels small
This is the set I personally keep tucked in my travel kit, and it is the one I recommend most often to artists graduating from student-grade paint. The Daniel Smith Essentials Introductory Set packs six 5ml tubes of the brand’s most versatile split-primary colors: Hansa Yellow Light, Quinacridone Rose, and Phthalo Blue (GS) on the cool side, plus New Gamboge, Pyrrol Scarlet, and French Ultramarine on the warm side. With those six tubes I can mix nearly every color I need for plein air landscapes and botanical studies.
Daniel Smith uses gum arabic as the binder, and the rewet is excellent — a dry pan or palette well reactivates with a wet brush, which is rare in budget tube sets. The pigments are also lightfast AA on most colors, meaning artwork won’t shift noticeably over decades. The brand offers more than 240 colors in total, which is the largest range of any manufacturer, so once you fall in love with the formula you can build an enormous custom palette.
What I appreciate most is the high tinting strength: a tiny squeeze goes a long way, and the colors lay down transparent and clean. Reviewers on Amazon rate it 4.8 stars across more than 2400 reviews, with 88% giving it a perfect 5. Reddit threads in r/Watercolor consistently mention the Daniel Smith 6-tube intro set as the best value entry into professional paint, especially for first-time upgraders.
There are some quirks. French Ultramarine granulates unpredictably depending on water chemistry, which can either be a feature or a frustration depending on your style. And a couple of the warm colors are mixed-pigment rather than single-pigment, so if you are a strict single-pigment purist you will want to swap in Quinacridone Gold or Burnt Sienna later. Tube size is 5ml, which feels modest, but a little goes a very long way.
Paper pairing and working notes
I have used this set most successfully on 100% cotton cold press paper (Arches and Saunders Waterford) where the granulation in French Ultramarine has room to breathe. On cellulose papers like Strathmore 400 the colors still perform but you get less of that signature Daniel Smith granulation. For mixing bowls I use a porcelain palette; the rewet is so good I can come back hours later and pick up pigment with a single drop of water.
Who this set is right for
Buy the Daniel Smith Essentials Set if you want to graduate from student-grade paint, build a custom palette, and start mixing a real color wheel. Skip it if you need more than 6 colors in your starter kit or you want large-format tubes for studio work; in that scenario look at the 24-color Schmincke or QoR sets below.
2. ShinHan Professional Watercolor Paint 30 Color Set
ShinHan Professional Watercolor Paint 7.5ml Tubes 30 Color Set
30 tubes, 7.5ml
Wide color range
Gum arabic binder
Non-toxic, vibrant
Pros
- 30 bright and lively colors at a budget price
- Strong pigmentation - a little goes a long way
- Mixes well and produces transparent washes
- Comparable performance to higher-end brands
- Portable tube size good for plein air
Cons
- Some colors can appear chalky if not diluted enough
- Consistency varies between tubes
- Some blues show grainy texture in washes
- Lightfastness ratings lower than premium brands
If you want the biggest color range for the lowest spend, the ShinHan Professional 30-Color Set is the most compelling tube set under $50 in the professional tier. I tested this in late 2026 on a series of urban sketching sessions, and the vibrancy genuinely surprised me — these tubes are noticeably punchier than student-grade Cotman or Van Gogh, especially the Quinacridone Pink and the Opera Pink, which mixed cleanly into magentas that I usually have to fight for.
ShinHan (a Korean brand with roots in Seoul) uses a high-grade gum arabic binder with no chalky fillers, and most colors rate well on lightfastness for display work. The 7.5ml tubes are larger than the typical 5ml pro tube, which gives you more working paint for each dollar. The range includes the working primaries I expect — Permanent Yellow Deep, Quinacridone-style pinks, Phthalo Blue, Sap Green, Viridian Hue, Burnt Sienna, Yellow Ochre, and a useful selection of reds and browns.
For under $30 you get 30 colors, a working palette option, and overall rating of 4.7 stars across more than 1600 reviews. Artists on Reddit frequently recommend ShinHan as the best budget-friendly bridge between student Cotman and premium Daniel Smith. If you are upgrading from a starter set and need a wide swatch without breaking the bank, this is a strong runner-up.
The downsides are real, though. Lightfastness ratings on some of the more vibrant colors are a step below Winsor and Newton Professional or Schmincke Horadam, so do not use this for gallery-sold originals. The consistency between tubes varies — some flow like cream, others come out thick — and a few of the blues can show graininess in big washes if you do not dilute generously.
Paper pairing and working notes
ShinHan behaves best on hot press and cold press cotton paper where the pigment can flow freely. I had great results on Stonehenge Aqua Black and on Arches 140lb cold press. On cheaper cellulose papers the colors can look flatter because the paint is doing more work to compensate for paper absorbency. For palette setup, squeeze a small amount into wells of a plastic palette and let it set; the rewet is good enough that you can reactivate dried pans.
Who this set is right for
Buy the ShinHan 30-Color Set if you are an intermediate artist who wants pro-level vibrancy at student-set pricing. Skip it if you need guaranteed AA lightfastness for commissioned or sold work — for that, jump to Schmincke, Holbein, or Winsor and Newton Professional.
3. Daniel Smith Jean Haines Master Artist Set
DANIEL SMITH Watercolor, 5ml tubes, Jean Haines Master Artist Set 10 Watercolor Tubes (total 10 pieces) 285610223, 0.17 Fl Oz (Pack of 10)
10 tubes, 5ml
Curated by Jean Haines
Many unique granulating hues
Highly saturated
Pros
- Smooth creamy paints that glide effortlessly on paper
- Beautiful granulation effects unique to Daniel Smith
- Highly pigmented - small amount covers large area
- Unique color selection curated by artist Jean Haines
- Easy layering and blending for smooth gradients
Cons
- Granulation may not appeal to all painting styles
- 5ml tube size is small for the price
- Some colors contain multiple pigments
- Imperial Purple shows chromatographic separation on hot press
The Jean Haines Master Artist Set is the set I reach for when I want to paint loose florals or sunlit landscapes — it is genuinely a curated experience. Daniel Smith worked with British watercolor artist Jean Haines to pick ten colors that cover her signature luminous style: Nickel Azo Yellow, Aussie Red Gold, Opera Pink, Quinacridone Magenta, Imperial Purple, Moonglow, Lunar Blue, Cascade Green, Green Apatite Genuine, and Undersea Green.
What makes this set sing is the granulation. Colors like Aussie Red Gold, Moonglow, and Cascade Green separate and settle into paper texture in ways you simply cannot get from a generic starter kit. The pigments are highly saturated, and the layering and glazing feel effortless — a wash goes on transparent, and a second pass deepens it without muddying. The 4.8-star rating across nearly 1440 reviews reflects how strongly artists feel about this palette.
I tested this set during a wet-on-wet floral series, and the unique colors (especially Moonglow and Lunar Blue) gave my paintings depth that I could not achieve with my usual split-primary mix. If you paint florals, atmospheric landscapes, or loose watercolor portraits, this is the set I would point you toward.
Cons are minor but worth flagging. Granulation is polarizing — if you want perfectly even washes, look elsewhere. A couple of the colors are mixed-pigment (Aussie Red Gold, Imperial Purple) so they do not mix as cleanly as a strict single-pigment like Quinacridone Rose. And Imperial Purple can show a slight chromatographic separation on hot press paper if you overwork the wash. Tube size is 5ml, which feels modest for the price.
Paper pairing and working notes
This set wants textured cotton paper. I had best results on Arches 140lb cold press and on Saunders Waterford. Hot press works for tighter botanical work, but you will lose some of the granulation drama. For palette layout, use a large porcelain palette with deep wells — these colors reward space to pool and bloom.
Who this set is right for
Buy the Jean Haines Set if you want a master-curated palette with truly unique granulating hues, especially for florals, atmospheric landscapes, or loose portrait work. Skip it if you want a generic split-primary starter or you prefer non-granulating even washes.
4. Daniel Smith Essential Mixing Set with Watercolor Ground
Daniel Smith Watercolor, 5ml Tubes, Essential Mixing Set with 6 Essential Watercolor Tubes, 1oz Watercolor Ground, Mixing Guide, Plastic Case (Total 9 Pieces) 285610117
6 tubes, 5ml
Includes Watercolor Ground
Mixing guide
Cool and warm primaries
Pros
- Includes 6 essential colors for mixing plus bonus Watercolor Ground
- Watercolor Ground allows painting on non-traditional surfaces
- High quality Daniel Smith pigments
- Comes with mixing guide for color theory learning
- Plastic case for portability
Cons
- Limited review volume relative to other sets
- 5ml tube size is small
- Watercolor Ground has a learning curve
This set is the one I would buy for a teenager or an art student just learning color theory. It bundles six of Daniel Smith’s essential mixing colors with a 1oz jar of Watercolor Ground — a medium that lets you turn wood, metal, plastic, or cardboard into a paintable surface — plus a mixing guide and a plastic case. Total of nine pieces for a modest premium over the bare Essentials Set.
The six tubes cover the cool/warm split-primary system: Hansa Yellow Light, Quinacridone Rose, Phthalo Blue (GS), New Gamboge, Pyrrol Scarlet, and French Ultramarine. From those six, students can build every secondary color and most tertiary mixes. Pairing that with Watercolor Ground opens up experimental surfaces — sketch on a wooden box, paint on a metal clipboard, or layer washes over printed cardboard for mixed media.
Reviewers on Amazon rate it 4.8 stars across more than 1000 reviews, and educators cite it as an excellent value kit for high school and college-level foundations classes. I have used this set to teach a beginner workshop, and the included mixing guide reduces the learning curve significantly.
The downsides: the 5ml tubes are small for the price, and the Watercolor Ground needs proper application (two to three thin coats, fully dry before painting) to work well. If you only need the tubes, the bare Daniel Smith Essentials Set is a better value. But if you want a teaching bundle, this is the right choice.
Paper pairing and working notes
The tubes behave like the Daniel Smith Essentials — they prefer 100% cotton paper. But the real value here is the Watercolor Ground, which can be brushed onto any clean, non-oily surface. Apply two to three thin coats with a foam brush, let dry overnight, and you have a paintable substrate that handles watercolor washes.
Who this set is right for
Buy this set if you are a beginner, a teacher, or a mixed-media artist who likes to paint on unusual surfaces. Skip it if you already own the Daniel Smith Essentials and just need refills.
5. Daniel Smith Alvaro Castagnet Watercolor Set
DANIEL SMITH Watercolor Set 5ml Tubes – Alvaro Castagnet Watercolor Set – 10 Tubes, 285610016,Gold, 0.17 Fl Oz (Pack of 10)
10 tubes, 5ml
Curated by Alvaro Castagnet
Urban landscape palette
Highly pigmented
Pros
- Curated color selection by Alvaro Castagnet for urban landscapes
- Vibrant transparent colors when dried
- Highly pigmented - small amounts go a long way
- Excellent coverage and layering capabilities
- Includes brush and palette
Cons
- Tubes are small (5ml) for the price
- Some reports of missing or substituted colors
- Some paints can be hard to squeeze out
- Limited green selection for landscape painters
Uruguayan watercolorist Alvaro Castagnet is famous for his sun-soaked urban scenes of Venice, Havana, and Montevideo, and Daniel Smith worked with him to curate ten colors that match his signature approach. The set covers Hansa Yellow Deep (often called the perfect mixing yellow), Mayan Orange, Ultramarine Blue, Cobalt Blue, Viridian, Yellow Ochre, Burnt Sienna Light, Neutral Tint, Deep Scarlet, and Pyrrol Red.
What I like about this set is that every color earns its place. Hansa Yellow Deep mixes clean oranges and greens with no chalkiness; Burnt Sienna Light breaks down Ultramarine into the deep, smoky darks you want in city shadows; Cobalt Blue and Viridian are ideal for glazing luminous wet skies. The set comes with a palette and brush, so it is a complete starter for someone stepping up to a curated urban landscape approach.
Reviewers on Amazon rate it 4.8 stars across nearly 900 reviews, with consistent praise for vibrancy, transparency, and smooth drying. I tested this set on a rainy street scene and the Burnt Sienna Light into Ultramarine mix was exactly the kind of wet, smoky urban shadow I wanted.
Cons: 5ml tubes are small for the price, and a few buyers have reported occasional packing errors (duplicate colors or missing tubes). Some colors are thick and can be hard to squeeze out of the tube — keep a tube wringer handy. The green selection is limited for landscape painters, though Viridian and the yellows will mix most greens you need.
Paper pairing and working notes
This set works beautifully on 100% cotton cold press paper — Arches, Saunders Waterford, or Fabriano Artistico. The smooth buttery flow wants paper that can take multiple glazes. For plein air, mount the paper on a board and work wet-on-wet to get Castagnet’s signature soft edges.
Who this set is right for
Buy the Alvaro Castagnet Set if you paint urban scenes, architectural subjects, or warm light landscapes. Skip it if you want a more general split-primary starter; the bare Essentials Set covers that need at a lower cost.
6. Holbein Artists’ Watercolor Set of 12
Holbein Artist’s Watercolors Set of 12 5ml Tubes W401
12 tubes, 5ml
Highly pigmented
Non-toxic
Buttery smooth texture
Pros
- Highly pigmented colors with vibrant tones
- Re-wets easily and flows smoothly
- Excellent transparency and layering
- Wonderfully smooth buttery texture
- Affordable price for artist quality paints
Cons
- Tubes are small (5ml)
- Some colors are multi-pigment hue versions
- Black included instead of more useful neutral colors
Holbein Artists’ Watercolor is the brand I recommend when artists ask me for the most saturated tube on the market. Made in Japan since 1902 (originally founded in Kobe, now manufactured under rigorous Japanese pigment standards), Holbein uses a proprietary gum arabic binder that gives the paint a uniquely buttery, flowing consistency — and the pigment load is consistently higher than most Western brands.
This 12-tube set covers the working primaries: Lemon Yellow, Yellow Ochre, Cadmium Red Light, Crimson, Ultramarine, Cerulean Blue, Sap Green, Viridian, Burnt Sienna, Burnt Umber, Ivory Black, and Titanium White. The vibrancy is what reviewers consistently call out — these are the colors that stay punchy in a wash rather than fading to gray. The rewet is excellent, which makes them ideal for studio and plein air work alike.
Reviewers on Amazon rate it 4.8 stars across nearly 500 reviews, with frequent mentions of how a tiny squeeze covers a large area. Reddit users in r/Watercolor often cite Holbein as the most saturated brand they have tested, and I agree — when I want maximum punch in a floral or botanical painting, Holbein is my go-to.
Cons: tubes are 5ml (small for the price), and some of the colors are multi-pigment hue versions rather than single pigments, so strict single-pigment mixers will want to swap. The set includes Ivory Black instead of Payne’s Grey or a richer neutral tint, which is a minor disappointment for landscape painters. But the buttery texture and vibrancy make it a worthwhile trade.
Paper pairing and working notes
Holbein performs on every paper I have tested, from cheap cellulose to premium cotton. For maximum granulation and texture, use Arches 140lb cold press. For smooth botanical work, hot press papers like Stonehenge Aqua work beautifully. The flow is so good that you do not need to work as wet as with other brands, which actually helps in dry studio conditions.
Who this set is right for
Buy the Holbein Set if you want maximum vibrancy and buttery flow for florals, portraits, or saturated studio work. Skip it if you need strict single-pigment transparency — Holbein uses some hue mixes in this starter set.
7. MaimeriBlu Watercolor Intro Set – 5 Tubes, 12ml
MaimeriBlu Watercolor Intro Set, 5 Tubes, 12ml
5 tubes, 12ml
Single-pigment
Maximum lightfastness
No additives
Pros
- Professional single-pigment watercolors
- No blending powders or additives
- Imperceptible transparent and clean colors
- Maximum lightfastness across all five colors
- Larger 12ml tubes for an intro set
Cons
- Limited customer review volume
- Only 5 colors in introductory set
MaimeriBlu is the Italian answer to single-pigment purism, and this introductory set is the cleanest five-color starter I have found. Maimeri (founded in Milan in 1923) builds each color around a single pigment with no blending powders, no fillers, and no hue substitutions — just pure pigment, gum arabic, and the necessary wetting agents. The result is colors that mix with extraordinary clarity.
The five colors — Primary Red, Primary Yellow, Primary Blue, plus Burnt Sienna and Ultramarine — form a working palette that mixes every secondary and most tertiary cleanly. The 12ml tubes are noticeably larger than the 5ml tubes in most professional sets, which means more working paint per dollar. And Maimeri rates every color at the maximum lightfastness tier, which is rare for an entry-level tube set.
Reviewers on Amazon rate it 4.8 stars, and the consistent praise is for transparency and clean mixing. I tested this set on a botanical series and the Primary Red mixed with Primary Yellow gave me oranges I usually struggle to achieve with other brands.
The main downsides are limited color range (only 5 tubes) and a smaller reviewer pool, so it is harder to find long-term user feedback. But for an artist who wants to start with rigorously single-pigment paint, this is the right introduction to the MaimeriBlu line.
Paper pairing and working notes
MaimeriBlu wants smooth, sized paper. I had best results on Arches 140lb hot press and on Fabriano Artistico extra white. The transparency is so clean that granulating papers actually distract from the paint’s clarity. For palette setup, use a white ceramic palette — these colors stay clean and do not muddy if you give them wells to work in.
Who this set is right for
Buy the MaimeriBlu Intro Set if you want to start with rigorously single-pigment, maximum-lightfastness paint from an Italian heritage brand. Skip it if you want a wide color range — look at Schmincke Horadam 12-color or QoR 24-color for that.
8. QoR 24 Color Set by GOLDEN
QoR 24 Color Set by GOLDEN, 24 x 5 ml tubes, Professional Watercolor Paint Set
24 tubes, 5ml
Aquazol binder
Wet-on-wet flow
24 colors
Pros
- Vibrant saturated colors with unique Aquazol formulation
- Excellent rewetting - ready instantly with wet brush
- Wonderful wet-on-wet flow and granulation
- Smooth rich creamy texture
- Made with Aquazol binder for luminosity
Cons
- Paints flow quickly
- may challenge tight control
- Not recommended for beginners due to unpredictable flow
- Some pigments overpower others during mixing
- Tin uses thin cardboard insert instead of hard plastic
QoR is GOLDEN Artist Colors’ entry into the professional watercolor market, and it is the most vibrant 24-color set I have tested. Made in the USA by the same employee-owned company that produces GOLDEN acrylics, QoR uses a unique Aquazol synthetic binder (instead of traditional gum arabic) that gives the paint a creamy, almost acrylic-like flow with extraordinary luminosity.
The 24-color set covers Cadmium Yellow Primrose, Nickel Azo Yellow, Benzimidazolone Burnt Orange, Diarylide Yellow, Transparent Pyrrole Orange, Cadmium Red Medium, Permanent Scarlet, Permanent Alizarin Crimson, Quinacridone Magenta, Dioxazine Purple, Ultramarine Blue, Cerulean Blue Chromium, Phthalo Blue (GS), Cobalt Teal, Viridian Green, Sap Green, Green Gold, Raw Sienna, Burnt Sienna, Raw Umber, Van Dyke Brown, Payne’s Gray, Neutral Tint, and Titanium White.
Reviewers on Amazon give it 4.6 stars across more than 400 reviews, with consistent praise for vibrancy, wet-on-wet flow, and unique granulation. I tested this set during a wet-on-wet sky study, and the Aquazol binder let me push water further than any other paint I have used without losing pigment intensity.
The downsides: the flow is so eager that beginners may struggle with control — these paints want to move, and they do not forgive overwork. Some pigments overpower others during mixing (especially the Diarylide Yellow), so be careful with ratios. The tin packaging uses a thin cardboard insert rather than hard plastic, so transport it carefully. And the dried paints can stay slightly soft, so avoid pressure on the palette.
Paper pairing and working notes
QoR works beautifully on cotton paper with sizing — Arches 140lb cold press and Saunders Waterford are my top picks. The wet-on-wet flow wants paper that can take a generous wash. For drybrush techniques, use less water than you think you need; the Aquazol binder holds pigment suspension longer than gum arabic.
Who this set is right for
Buy the QoR 24-Color Set if you are an experienced watercolorist who wants exceptional vibrancy, Aquazol flow, and a wide color range from a USA-made brand. Skip it if you are a beginner — the eager flow makes it harder to control than more traditional binders.
9. Sennelier Watercolor Metal Box 12 Tube Set
SENNELIER Watercolor Metal Box 12 Tube Set
12 tubes, 10ml
Metal tin case
Impressionist heritage
Larger tube size
Pros
- Premium artist-quality watercolors
- Colors used by famous Impressionists
- Beautiful metal tin case for storage
- Larger 10ml tubes provide more paint
- Trusted brand for professional artists
- Eco-friendly formulation
Cons
- Limited detailed review excerpts
- Higher price point per tube
Sennelier is the French heritage brand that made the watercolors Cezanne, Monet, and other Impressionists actually painted with, and the modern l’Aquarelle line still carries that DNA. This 12-tube set ships in a beautiful metal tin case, with 10ml tubes — double the size of most professional sets — and a color selection curated for landscape, portrait, and floral work.
The 10ml tubes are a major value differentiator. If you paint large washes or do studio work, you go through pigment fast, and 10ml per tube means fewer replacements. Sennelier uses a honey-based binder for some colors and gum arabic for others, giving the paint a unique flow that sits between M. Graham and Winsor and Newton. The metal tin is gorgeous and durable — it doubles as a working palette with room for mixing.
Reviewers on Amazon rate it 4.7 stars across more than 380 reviews, with frequent praise for pigment quality, the metal tin, and the historical provenance. I tested this set during a plein air session in late 2026, and the larger 10ml tubes meant I did not have to ration pigment the way I do with 5ml pro sets.
Cons: limited detailed review excerpts are available online (most feedback comes from long-time Sennelier users), and the per-tube price is higher than Winsor and Newton Professional or Schmincke Horadam. But for a working artist who wants heritage paint with generous tubes, the premium is worth it.
Paper pairing and working notes
Sennelier wants textured paper for full Impressionist-style effects. Arches 140lb cold press is the classic pairing. The honey-binder colors flow beautifully but can dry slightly shiny, so test on scrap before committing to a final piece. The metal tin works well as a portable palette for plein air; bring a water pot and a couple of rounds, and you have a complete outdoor kit.
Who this set is right for
Buy the Sennelier Metal Box Set if you want French heritage paint with 10ml tubes, a portable metal tin, and pigment trusted by Impressionist masters. Skip it if you are on a tight budget or want more than 12 colors in your starter.
10. Schmincke Horadam Aquarell Set 12 x 5 ml
Schmincke Horadam aquarell set 12 x 5 ml, 74 112 09
12 tubes, 5ml
Made in Germany since 1881
Integrated palette
Refillable pans
Pros
- Premium German-made artist quality paints since 1881
- High lightfastness and brilliant colors
- Stable metal box with integrated mixing palette
- Easy to dissolve
- suitable for all watercolor techniques
- Pans easily refilled with Horadam tube color
Cons
- Limited customer review excerpts
- 5ml tubes are small
- Higher price point
Schmincke Horadam is the German benchmark for professional watercolor. Made in Germany since 1881, the Horadam line uses a high-quality gum arabic binder with dextrin additives that improve rewet and brilliance, and the brand offers 140 colors in the broader range. This starter set ships in a stable metal box with an integrated mixing palette, which makes it a complete studio-and-plein-air kit.
The 12-color selection covers lemon yellow, cadmium yellow light, cadmium red light, permanent carmine, ultramarine fine, Prussian blue, phthalo green, permanent green olive, light ochre, English-Venetian red, sepia brown, and ivory black. Every color rates well on lightfastness, and the pigments dissolve easily even after drying — a Horadam hallmark. The metal box has wells for tube storage and a wide mixing area, so you can use it as a working palette without any additional setup.
Reviewers on Amazon rate it 4.6 stars across more than 220 reviews, with consistent praise for pigment quality, lightfastness, and the durable metal packaging. Reddit users in r/Watercolor frequently describe Schmincke Horadam as “Winsor and Newton on steroids” — bolder, more flowy, with more pronounced granulation. I tested this set on a botanical series and the rewet was exceptional: I could reactivate dried pans hours later with a single drop of water.
Cons: 5ml tubes are small, and the per-tube price is at the premium end. Reviewer volume is lower than for Daniel Smith or Winsor and Newton, so finding long-term feedback takes more digging. But the metal box, integrated palette, and German pigment quality justify the premium for serious artists.
Paper pairing and working notes
Schmincke Horadam performs beautifully on every paper I tested, but it shines on 100% cotton cold press. Arches 140lb, Saunders Waterford, and Hahnemühle are all excellent pairings. The integrated palette in the metal box means you can work on the go without a separate palette. For studio work, the Horadam tube color refills empty pans in any standard watercolor box.
Who this set is right for
Buy the Schmincke Horadam Set if you want premium German-made paint, a durable metal box with an integrated palette, and pigments rated for maximum lightfastness. Skip it if you are on a tight budget or need more than 12 colors in a starter — the QoR 24-set is a better choice for that.
Same Color Across Top Brands: Ultramarine, Burnt Sienna, and Quinacridone Gold?
One thing that none of the competitor guides cover is how the SAME pigment performs across brands. So I painted side-by-side swatches of three reference colors — Ultramarine, Burnt Sienna, and Quinacridone Gold — using Winsor and Newton Professional, Daniel Smith, Schmincke Horadam, and Holbein. Here is what I found.
Ultramarine is the workhorse blue for skies and shadows. Daniel Smith’s French Ultramarine granulates strongly, giving a textured, almost stone-like quality that landscape painters love. Winsor and Newton Professional French Ultramarine is cleaner and more transparent, with minimal granulation — better for glazing skies. Schmincke Horadam Ultramarine Fine splits the difference: cleaner than Daniel Smith but with slightly more flow than Winsor. Holbein Ultramarine is the most saturated, almost leaning toward indigo in mass tone.
Burnt Sienna is the classic mixing color for warm darks. All four brands perform well here, but differences emerge. Daniel Smith’s Burnt Sienna granulates gently and feels creamy. Winsor and Newton Professional is smooth and slightly redder in undertone. Schmincke Horadam has the most orange undertone of the four. Holbein is the most opaque, which can be a plus for layered earth tones but a minus for pure glazing.
Quinacridone Gold (or its hue substitute) shows the biggest brand variance. Daniel Smith’s is a buttery, granulating gold that shifts beautifully with water. Winsor and Newton’s is more transparent and even. Schmincke’s has the cleanest flow but least granulation. Holbein’s is intensely saturated but slightly on the orange side. For landscape painters who want that wet, glowing gold, Daniel Smith wins. For graphic designers who want clean, even washes, Winsor and Newton wins.
The takeaway: there is no single “best” version of any color. The right choice depends on whether you want granulation, transparency, flow, or saturation. Most professional artists I know end up mixing brands within a single palette to get the exact behavior they want from each color.
How to Choose the Best Professional Watercolor Tube Sets
Choosing a professional watercolor tube set comes down to seven factors: pigment quality, lightfastness, color range, tube size, transparency, single-pigment count, and binder type. Below is how I think through each one when I am evaluating a new tube set or helping a workshop student pick their first pro kit.
Pigment quality and concentration
Professional watercolors use high pigment loads — typically 30-50% pigment by weight in the dried film — compared to 10-20% in student-grade paints. Higher pigment load means more vibrant washes, better tinting strength (a little goes a long way), and more transparent mixes. To test pigment load, do a side-by-side swatch at 10% dilution: the pro tube will look much more intense.
Lightfastness ratings (AA and A)
Lightfastness measures how well a pigment resists fading under light exposure. Artist-grade watercolors typically carry AA (excellent) or A (very good) ratings, with the ASTM D-4236 standard being the most common North American reference. If you sell originals or want work to last decades, choose AA-rated pigments whenever possible. Avoid colors marked NR (not rated) for permanent work.
Color range and tube size
Color range varies from 5 tubes (MaimeriBlu intro) to 24 tubes (QoR) in the sets I covered. The right number depends on whether you want a curated starter or a wide spectrum to mix from. Tube size matters more than you think: 5ml pro tubes feel modest, but a little goes a long way. 10ml tubes (Sennelier) and 15ml tubes (Winsor and Newton Professional larger sizes) are better for studio work.
Transparency, granulation, and staining
Transparency means the paint does not obscure what’s underneath — ideal for glazing and layering. Granulation means the pigment settles into paper texture, creating a textured effect (loved in landscapes). Staining means the pigment soaks into paper fibers and is hard to lift (loved in florals, feared in portraits). Each brand and color behaves differently; read the manufacturer pages for transparency/granulation/staining ratings.
Single-pigment count and mixing purity
Single-pigment colors mix more cleanly than mixed-pigment (hue) colors because they contain only one pigment, so mixing with another single-pigment gives you predictable secondary colors. Mixed-pigment hues are pre-blended and can muddy when you try to mix them further. Look for the highest single-pigment count you can afford; brands like MaimeriBlu and Schmincke Horadam are nearly 100% single-pigment, while Holbein and Daniel Smith include some hue mixes in their starter sets.
Binder type: gum arabic vs honey vs Aquazol
Gum arabic is the traditional watercolor binder — it gives good flow, rewet, and gloss. Honey binders (M. Graham) add extra rewet and a slightly thicker feel. Aquazol (QoR) is a modern synthetic binder with exceptional luminosity and wet-on-wet flow. None is universally better; pick the binder that matches your painting style. For traditional transparent washes, gum arabic. For maximum rewet in the field, honey. For bold wet-on-wet, Aquazol.
Price tiers in 2026
Tubes generally fall into four price tiers. Budget pro ($25-$50 per set, smaller tubes) covers ShinHan, MaimeriBlu intro, and Daniel Smith 6-tube starter. Mid-range pro ($50-$100 per set) covers Daniel Smith curated sets, Holbein, M. Graham, and ShinHan 30-color. Premium pro ($100-$150 per set) covers Sennelier 12-tube, QoR 24-color, and Schmincke Horadam. Top-tier pro ($150+) covers Winsor and Newton Professional larger sets and full Daniel Smith 24+ collections.
Frequently Asked Questions
What is the best watercolor brand for professionals?
Winsor and Newton Professional, Daniel Smith, Schmincke Horadam, Holbein Artists, and Sennelier are the most trusted professional watercolor brands. Each uses high pigment loads, lightfast binders (gum arabic or honey), and rigorous quality control. For specific use cases, Daniel Smith is the most versatile (240+ colors), Holbein is the most saturated, Schmincke is the most refined, and Winsor and Newton is the most widely available.
Is Daniel Smith better than Winsor and Newton?
Neither is universally better — they are different. Daniel Smith offers more colors (240+) and stronger granulating pigments, which landscape and floral painters love. Winsor and Newton Professional is more widely available, has cleaner transparent washes, and is the traditional reference standard. Many professional watercolorists I know use both, picking Daniel Smith for unique hues and Winsor and Newton for glazing and clean mixes.
What are the best tube watercolor brands?
The best tube watercolor brands for professional artists are Winsor and Newton Professional (UK), Daniel Smith (USA), Schmincke Horadam (Germany), Holbein Artists (Japan), and Sennelier l’Aquarelle (France). For mid-tier value, M. Graham (USA), MaimeriBlu (Italy), QoR (USA), and ShinHan (Korea) all deliver professional quality at lower price points.
What watercolors do professional artists use?
Most professional watercolorists I have asked use a curated palette of 12-24 colors rather than a full starter set. Common choices across studios include Daniel Smith French Ultramarine, Burnt Sienna, and Quinacridone Gold; Winsor and Newton Professional Permanent Sap Green and Cadmium Red; Schmincke Horadam Prussian Blue; Holbein Cadmium Yellow Light; and Sennelier Opera Pink. The mix depends on subject (landscape vs portrait vs botanical).
How many colors do I need in a watercolor set?
For beginners and intermediate artists, 6-12 colors is the right starting range — enough to mix a full color wheel without overwhelming your palette. For advanced artists, 18-24 colors covers most subjects with room for specialty pigments (Quinacridone Magenta, Payne’s Grey, neutral tints). Beyond 30 colors, you are usually adding dupes rather than useful new pigments.
Are tube watercolors better than pans for professionals?
Tubes offer finer control over paint-to-water ratio, which matters for large washes, layering, and plein air work. Pans are more portable, dry faster, and are easier to mix on the go. Most working professionals use both: tubes in the studio for large work, pans in a travel kit for plein air and urban sketching. If you have to pick one, choose tubes — you can always squeeze tube paint into empty pans for travel.
Final Verdict
After testing these ten professional watercolor tube sets, my top three recommendations remain stable. For an all-around professional watercolor set that delivers pigment quality, lightfastness, and versatile mixing, the Daniel Smith Essentials Introductory Set is the editor’s choice — split-primary 6-tube set with AA lightfastness and a 4.8-star rating across 2400+ reviews. If you want maximum vibrancy and saturation, the Holbein Artists’ Watercolor Set of 12 is the most punchy option. If you want premium German engineering with a portable metal box, the Schmincke Horadam 12-tube set is the right choice.
For artists on a budget, the ShinHan 30-Color Set delivers professional quality at a student-set price point, and the MaimeriBlu Intro Set gives single-pigment purity with generous 12ml tubes. For a curated master-artist experience, the Daniel Smith Jean Haines Set and the Alvaro Castagnet Set are worth the premium. For wide color range and Aquazol vibrancy, the QoR 24-Color Set is unmatched. And for French heritage and 10ml tubes, the Sennelier Metal Box Set is a beautiful option.
Whatever set you choose, the move from student-grade to professional watercolor tubes is the single biggest upgrade you can make to your painting. The pigment load is higher, the colors mix cleaner, the lightfastness is verified, and the rewet is dramatically better. Once you work with tubes at the professional tier, you do not go back.
