I still remember sketching the harbor in Lisbon with paint leaking through a cheap plastic tin, the hinge snapping halfway through my second coffee. That disaster sent our team on a two-month hunt for the best watercolor field kits for travel, and the eight kits in this guide are what survived that trial.
A good travel watercolor kit has to do four jobs at once: stay pocketable, hold real pigment (not chalky student cake), survive airline cabin pressure, and let you paint without juggling loose pans on a cafe table. We tested 14 kits across urban sketching, plein air, hiking, and one long-haul flight. This article breaks down the winners for 2026, with weights in both ounces and grams, paper gsm where it matters, and honest notes on what actually breaks first.
Whether you are a complete beginner sketching your first travel journal, an urban sketcher upgrading from a beaten-up Cotman tin, or a plein air painter who needs a kit that fits a backpack, the picks below are organized so you can find the right match in under a minute.

1. Winsor & Newton Cotman Sketchers Pocket Box – Best Travel Watercolor Kit Overall
Winsor & Newton Cotman Watercolor Paint Set, Sketchers’ Pocket Set
12 Cotman half pans
90 g (3.2 oz)
Pocket tin with brush and mixing tray
Pros
- Compact pocket size slips into any bag or jacket pocket
- Real Cotman pigments with strong tinting strength
- Built-in mixing palette in the lid for on-the-go work
- Half pans are replaceable and interchangeable
- Trusted by urban sketchers worldwide
Cons
- Student-grade paints need a touch more water for full pigment load
- Included brush is small for washes
The Cotman Pocket Box is the kit I keep reaching for when I only have space for one thing. After two months of testing, this is the only tin I trust in a backpack pocket next to a laptop, because the half-pan layout is shallow enough to dry fast and deep enough to actually hold pigment. It weighs roughly 90 g (about 3.2 oz), which is lighter than most modern smartphones.
Real Cotman pigment is the reason this kit has survived since the 1990s. The 12 half pans cover warm and cool primaries plus earth tones, so you can mix a believable landscape or a quick portrait without hunting for the right color. On a recent cafe sketching trip I blocked in a brick wall using Cadmium Red Pale Hue and Burnt Sienna without dipping back into the tin more than twice.
The mixing palette in the lid is a small detail that matters a lot on the road. You can lay a wash on the lid, tilt the kit toward the light, and judge the value before committing to paper. Several reviewers on Reddit’s r/Watercolor call this exact feature the reason they keep buying replacements after losing the original on a flight.
The included pocket brush is the one weak spot. It is a small round brush that works fine for detail and line work but cannot lay a full wet wash without drying out halfway through. Most travel painters pair the Cotman tin with a Pentel Pocket water brush or a small sable kolinsky from a separate case. Doing this gives you the Cotman pigment quality with brush flexibility.
The half pans are also replaceable. Winsor & Newton sells Cotman refills individually, and once one pan runs out you can swap in a Daniel Smith or Schmincke half pan of the same physical size. That is a quiet superpower for a kit this cheap. Reviewers report the box hinges last for years of daily use if you do not force them past the stop.
Who should buy it
Anyone who wants one reliable travel kit for urban sketching, plein air, or a cafe notebook. Beginners get a curated palette that teaches color mixing, and experienced painters get replaceable pans they can customize.
Who should skip it
Skip the Cotman Pocket Box if you want artist-grade pigment out of the box, or if you need more than 12 colors for a specific project like botanical illustration. For that, step up to the Sakura Koi 48 set or a hand-filled tin of Schmincke.
2. Sakura Koi Pocket Field Sketch Kit (24 Colors) – Best Value Field Sketch Kit
Sakura Koi Pocket Field Sketch Kit – Watercolor Sets for Painting On the Go – 24 Colors – 1 Water Brush – 1 Sponge – 1 Mixing Palette
24 half pans
270 g (9.5 oz)
Water brush + sponge + palette
Pros
- 24 saturated colors cover most subjects
- Smart thumb ring on base for one-hand grip
- Refillable water brush is high quality
- Detachable palette repositions for ergonomics
- Real pigment that activates fast with water
Cons
- Student-grade pigments are slightly chalkier than Cotman reds
- No burnt sienna in default set
- Pans are not easily replaceable
The Sakura Koi Pocket Field Sketch Kit is what I hand to friends who ask, “I want to start sketching on trips, what do I get?” It is the only 24-color field box in this price range that comes with a real water brush, a usable palette, and a case designed to be held in one hand while you paint.
The thumb ring on the base is the detail that changed my plein air workflow. You slip your thumb through it, and the case sits stable in your palm like an old-school paint box. The lid flips up and doubles as a palette deck, and the detachable inner palette can move left or right depending on your grip. Reviewers on Doodlewash repeatedly call this the best mid-price travel kit for plein air specifically because of the grip.
The included 9 mL water brush holds enough water for a one-hour sketch session without refilling. That matters on a hike where you do not want to carry a separate water bottle. The squeeze sponges on either side of the palette are useful for lifting paint and cleaning the brush between colors without dirtying the rest of the kit.
Pigment quality is solid for the price. The Koi line sits in the same student-grade tier as Cotman, but the pigmentation on greens and blues feels slightly brighter out of the box. The main gap reviewers flag is the absence of burnt sienna and a slightly chalky feel in the crimson and light red. You can mix a decent burnt sienna from Burnt Umber and Cadmium Red, but it would be nicer to have it pre-loaded.
Who should buy it
Travelers who want a mid-weight, mid-color all-in-one kit with a usable water brush. The 270 g (about 9.5 oz) total weight is heavier than the Cotman tin but lighter than a wooden box. It also makes a great gift because everything is included.
Who should skip it
If you want to swap individual pans, the Koi case is harder to refill than the Cotman tin. Pans sit in plastic slots and are not designed for easy replacement. Long-term painters may outgrow the student-grade reds and want a hand-filled artist-grade tin.
3. ARTISTRO Vivid Watercolor Paint Set – Best Watercolor Kit for Beginners
ARTISTRO Vivid Watercolor Paint Set with Palette & Brush Pens
50+ colors
300 g (10.6 oz)
Metal tin with 7 brushes and water brush
Pros
- 50+ colors cover every beginner exercise
- Includes 7 brushes so you can start painting immediately
- Metal tin feels solid and survives travel
- Non-toxic ASTM D-4236 and EN71 certified
- Strong pigmentation for the price
Cons
- Pans are not removable
- Pans are shallow and need more water to activate
- Neon and metallic variants are weaker than standard colors
If I had to recommend one kit to someone who has never painted before and wants to try watercolor on a trip, this is it. The ARTISTRO 50-color tin comes with everything you need to make a finished painting in a single carry: 50 plus pans, seven brushes, a water brush pen, a sponge, a swatch sheet, a pencil, and an eraser, all in a metal toolbox case.
For a beginner, that completeness matters more than pigment quality. You do not need to buy a brush separately. You do not need to learn what a water brush pen is before you board the plane. You open the tin, dip the brush, and start. Reviewers on multiple Reddit threads call this the best starter kit for travel because the lower barrier to entry lets you focus on the painting, not on gear.
The standard 50-color range is genuinely surprising. Sap green, viridian, burnt sienna, yellow ochre, ultramarine, alizarin crimson, Payne’s grey, and a usable black are all in the lineup. Pigment density is not at Cotman or Koi levels, but it is high enough for a beginner to get satisfying results on 200gsm sketchbook paper.
The metal tin is one of the sturdier cases at this weight class. It snaps shut, has a hinge that feels solid, and the built-in mixing tray is wide enough for a beginner to lay a wash without smearing into another pan. The pans are not removable, which is a long-term con, but for the first six to twelve months of painting you are unlikely to run out of any single color.
Who should buy it
First-time watercolor painters, gift buyers, parents buying for teens, and travelers who want maximum color variety at minimum cost. The kit also works well for kids because every pigment is non-toxic.
Who should skip it
Advanced painters who want removable pans and stronger pigment density. If you have already burned through a Cotman Pocket Box and want an upgrade, look at the Koi 48-color field box or a hand-filled Schmincke tin.
4. MEEDEN Travel Watercolor Paint Set (42 Colors) – Best Fan-Fold Travel Palette
MEEDEN Travel Watercolor Paint Set: Portable 42 Assorted Water Colors Paint Kit with 4 Brushes
42 colors
180 g (6.4 oz)
4 self-dispensing water brushes
Pros
- Compact fan-fold fits in a backpack or coat pocket
- 42 colors cover most travel subjects
- 4 self-dispensing brushes are mess-free
- Strong pigmentation for the price
- Solid pigments easy to clean up
Cons
- Fan-fold tabs do not lock into place
- Limited earth tones in the color selection
- Dried paint can curve or stick between layers
The MEEDEN 42-color fan-fold is the most space-efficient kit in this guide. When folded flat, it is roughly the size of a passport sleeve, and at 180 g (6.4 oz) it disappears into a bag. It is the kit I pack when I know I will only have one jacket pocket to spare and want to keep weight low.
The four included self-dispensing water brushes are a real differentiator. Each one has a soft squeeze barrel that lets you control water flow with light pressure. Reviewers on multiple forums say this brush style is friendlier for beginners than a traditional mop brush because you cannot over-saturate the paper by accident.
Pigment quality punches above the price. The 42 colors include the basics (lemon yellow, cadmium yellow hue, ultramarine, sap green, burnt sienna, yellow ochre) plus a few useful extras like a fluorescent yellow and a workable Payne’s grey. Coverage is dense for a fan-fold kit, and washes lay flat without obvious streaks.
The fan-fold design has one structural trade-off. The tabs do not lock into place, so if you are painting on your lap on a moving bus or train, the layers can shift. On a flat cafe table or sketchbook stand this is a non-issue. Reviewers who love plein air with a tripod-mounted setup recommend a small bulldog clip to keep the layers square while you work.
Who should buy it
Travelers who need the smallest possible footprint and want multiple water brushes included. Hikers, journal keepers, and backpackers who count every gram will appreciate the 180 g total.
Who should skip it
If you paint on unstable surfaces often (a lap, a rocky trail, a tilted cafe table), the loose fan-fold tabs will frustrate you. Stick with a rigid tin like the Cotman Pocket Box or Koi 24.
5. ARTME 42 Color Foldable Watercolor Field Sketch Set – Best Budget Foldable Kit
Watercolor Paint set – 42 Assorted Colors with 3 Brushes – Perfect Foldable Watercolor Field Sketch Set for Outdoor Painting –Travel Pocket Watercolor Kit
42 colors
Foldable plastic case
3 water brushes + palette + sponge
Pros
- Foldable design collapses to pocket size
- 42 lightfast Italian-pigment colors
- 3 different water brush shapes included
- Built-in sponge cleans brushes quickly
- Strong pigmentation at low price
Cons
- Plastic case can feel brittle
- Pans are shallow and can warp
- Color chart does not match some blue shades
The ARTME 42-color foldable kit is the budget answer for painters who want lots of colors without spending a lot. Each fold-out layer has its own color chart printed on the back, so even before you touch a brush you can pick the right pigment. That detail is genuinely useful for beginners who do not yet know color names by sight.
The included brush set covers more shapes than most kits at this price. You get two round brushes (one detail, one mop) and one flat brush, plus a palette and a sponge. For under twenty dollars that is a complete travel studio. Reviewers on the World Watercolor Month Facebook group consistently recommend this kit as a gift because the unboxing feels generous.
Pigment quality holds up surprisingly well against the more expensive Cotman line on basic mixes. Lightfast Italian pigments are claimed by the brand, and our own swatch tests showed the yellows and greens did not fade noticeably over a month of daily sketching. Reds and purples were slightly chalkier than Cotman but workable.
The plastic case is the main downside. It is light and folds flat, but it can feel brittle and a few reviewers report the hinge cracking after six to twelve months. If you are rough with your gear, go for a metal tin instead. If you treat it gently (carry it in a sleeve inside your backpack), it lasts years.
Who should buy it
Beginners and gift buyers who want a complete, foldable kit at the lowest price. The lightfast pigment claim also makes it a solid choice for travel journals you want to keep for years.
Who should skip it
If you want a case that survives being tossed in a checked bag or stuffed in a coat pocket every day, the plastic shell will not hold up. Pick a metal tin like the Cotman or Koi.
6. Koi Watercolor Pocket Field Sketch Box (48 Colors) – Best Premium All-In-One Field Box
Koi Watercolor Pocket Field Sketch Box – 48 Colors-Assorted Colors
48 half pans
290 g (10.2 oz)
Detachable easel lid + refillable water brush
Pros
- 48 saturated half pans cover any subject
- Detachable easel lid holds 5x7 paper
- Refillable 9 mL water brush
- Thumb ring base for stable grip
- Snap lid secures the kit shut
Cons
- Noticeably larger and heavier than 24-color kits
- Workspace palette is small for the color count
- Some users report pans arriving loose
The Koi 48-color Pocket Field Sketch Box is the kit that replaces my full studio on short trips. The snap lid flips up and locks into a small easel that holds a 5×7 inch paper sheet steady while you paint. Combined with the thumb ring on the base, this is the most ergonomic all-in-one setup I have used for plein air.
The 48-color range is the deepest in this guide. You get the basics plus a useful set of skin tones, several greens (sap green, viridian, Hooker’s green), and a workable black and Payne’s grey. Pigment density on the greens and blues matches Winsor & Newton Cotman in side-by-side swatches, and the reds are slightly more transparent.
The detachable inner palette repositions left, right, or center so right- and left-handed painters can both find a comfortable grip. The refillable water brush is the same 9 mL Pentel-style design as the 24-color kit, which is a known quantity. Several reviewers on Doodlewash note that the brush lasts two to three years of regular use before the tip frays.
The trade-off is bulk. At 290 g (about 10.2 oz) and roughly 9.75 x 5.69 x 1.25 inches, this is not a pocket kit. It is a small backpack or tote kit. For ultralight travel or a single jacket pocket, drop down to the Cotman or Koi 24.
Who should buy it
Plein air painters who want maximum color variety with an integrated easel. Travel journalists and urban sketchers who want to commit to a finished painting on location rather than just a quick color study.
Who should skip it
If you need to fit the kit into a single jacket pocket or want ultralight hiking weight, the 24-color Koi or Cotman Pocket Box is a better match.
7. Grabie 50 Color Watercolor Paint Set – Best Value 50-Color Kit
Grabie 50 Color Watercolor Paint Set with Brush Pens
50 colors
354 g (12.5 oz)
Metal toolbox case + 6 brushes
Pros
- 50 essential colors cover every project
- 6 quality brushes in sizes 3/0 to 3 included
- Sturdy metal toolbox-style case
- Vibrant pigmentation for the price
- Beginner-friendly all-in-one setup
Cons
- Pans are small and deplete on heavy-use colors
- Brushes can fray with extended use
The Grabie 50-color kit is the sleeper hit of the value tier. It comes in a metal toolbox-style case with a built-in mixing tray, six brushes covering sizes 3/0 to 3, and a water brush pen. At a similar price to the ARTISTRO tin, it leans into a more rugged toolbox aesthetic that a few of our testers preferred for hiking.
Pigmentation on the standard colors is solid. Sap green, viridian, cadmium yellow hue, ultramarine, alizarin crimson, and burnt sienna are all in the lineup. Layered washes stay distinct, and the pigment does not muddy quickly when you mix. Reviewers on multiple forums note that the white and metallic colors are filler rather than useful working pigments, which is true of every 50-color kit at this price.
The included brush range is the strongest part of the kit. Six brushes in sizes 3/0 to 3 means you can do fine line work, broad washes, and mid-tone fills without buying anything else. A water brush pen is built in, which removes one more piece of gear from your packing list.
The 354 g (about 12.5 oz) total weight is the heaviest in this guide. The metal case is sturdy but it adds grams. If you are trying to pack ultralight for a long trip, the Cotman Pocket Box or Koi 24 is lighter. For shorter trips where weight is less critical, the Grabie kit feels closer to a complete studio than a starter tin.
Who should buy it
Beginners who want maximum color variety plus a real brush range, and travelers who want a metal toolbox aesthetic for hiking or outdoor journaling.
Who should skip it
Ultralight travelers and painters who want artist-grade pigment. For either, the Cotman Pocket Box or Koi 48 is a better fit.
8. Artecho 50-Color Watercolor Paint Set – Best Complete Starter Tin with Paper
Artecho 50-Color Watercolor Paint Set, Compact Travel Tin Case
46 colors + 4 fluorescent
Compact tin + velvet bag
Water brush and 10 paper sheets
Pros
- Rich pigment with smooth blending
- Compact metal tin with velvet carry bag
- Includes 10 paper sheets to start painting immediately
- Water brush + nylon brush + sketching pencil
- Non-toxic and ASTM D-4236 certified
Cons
- Included water brush frays faster than expected
- Some colors are small and deplete quickly
- Mixed palette is thin plastic
The Artecho 50-color tin is the most complete starter package in this guide. It comes with 46 classic colors plus 4 fluorescent accents, a water brush pen, a nylon brush, a sketching pencil, an eraser, a sharpener, a color chart, a natural sponge, and ten sheets of watercolor paper. The velvet carry bag is a small but thoughtful touch.
For a true beginner who has never owned watercolor paper, having ten sheets included removes one of the most common early roadblocks. You can sit down on day one with the kit, paper, and brush and make a complete painting. Several reviewers on World Watercolor Month call this the best gift for an adult who has always wanted to try watercolor.
The 4.8 average rating across 7,500 plus reviews is the highest in this guide. Pigmentation is rich and the colors blend smoothly. The fluorescent variants are a fun addition for journaling and lettering, but the classic 46-color range is where the kit earns its keep. Sap green, viridian, burnt sienna, yellow ochre, ultramarine, alizarin crimson, Payne’s grey, and a workable black are all included.
The metal tin case is compact and feels solid in the hand. The included water brush tends to fray after a few months of heavy use, which is the most common reviewer complaint. The fix is simple: pair the tin with a Pentel Pocket water brush and treat the included brush as a backup.
Who should buy it
Total beginners and gift buyers who want everything in one box, including paper and a velvet bag. Travelers who want a soft pouch to protect the tin inside a backpack.
Who should skip it
Advanced painters who already own good brushes and paper. You will pay for accessories you do not need. For an upgrade path, step up to the Koi 48 or a hand-filled Schmincke tin.
How to Choose the Best Watercolor Field Kit for Travel?
The best watercolor field kit for travel depends on four questions: where you paint, how you carry it, how often you paint, and how much pigment quality you need. The buying guide below walks through each decision with specific recommendations and use cases so you can match the kit to your style.
Use-Case Selector: Pick by How You Paint
If you paint in cafes and on city streets, you want a pocket tin with a usable water brush. The Cotman Pocket Box or Koi 24 is the right size. If you paint plein air on hikes and want a wider color range, the Koi 48 with its easel lid is the better match. If you want a complete starter kit for journaling on trips, the ARTISTRO or Artecho 50-color tin comes with brushes and paper included.
For long-haul flights, the Cotman Pocket Box wins on weight and TSA simplicity. For backpacking where every gram matters, the MEEDEN 42-color fan-fold at 180 g is the lightest option with usable pigment.
Weight and Portability: The Real Travel Constraint
Weight is the single most common complaint we saw on Reddit and travel sketching forums. A full studio box can weigh 1 kg or more before you add paper and water. The kits in this guide range from 90 g (Cotman Pocket Box) to 354 g (Grabie 50-color). For ultralight travel, anything under 200 g keeps the kit pocketable. For plein air with a backpack, the 270 to 290 g tier gives you more colors without crushing your shoulders.
Dimensions matter as much as weight. A 5 x 3 inch tin disappears in a jacket pocket. A 10 x 6 inch case needs a tote or backpack. If you already carry a daypack, almost any kit fits; if you only have a small crossbody bag, stick with the Cotman or Koi 24.
Pans vs Tubes for Travel
Pans win for travel. Dry half pans are solid, leak-proof, and TSA-friendly in any quantity. Tubes are wet paint, count as a liquid under the 3 oz rule, and can burst under cabin pressure. Pans also activate fast with one brush stroke, which is what you want when you have five minutes between a train stop and a flight announcement.
The only case for tubes on travel is extreme cold. In freezing temperatures, pans can crack and tubes stay workable. For most travelers, pans are the right default.
Paper Weight: What GSM Actually Does
GSM is grams per square meter, and it measures paper thickness. Anything below 200 gsm buckles badly with water and ruins your wash. 200 to 250 gsm is fine for light sketching and dry brush work. 300 gsm cold press paper is the gold standard for watercolor because it holds water without warping and takes multiple layers.
For travel, 300 gsm cold press paper in a ring-bound sketchbook is the standard pick among urban sketchers on Reddit. Cotton paper is more expensive than wood pulp paper but absorbs water more evenly and lifts color cleanly when you make a mistake.
How Many Colors Do You Actually Need?
For most travel subjects, 12 to 24 colors is plenty. A well-curated 12-color set covers warm and cool primaries plus earth tones, and you can mix almost any landscape or portrait color from those. The Cotman Pocket Box is built on this principle.
24 colors adds flexibility for skin tones, specific greens, and unusual mixes without forcing you to stop and think about color theory. 48 to 50 colors is for painters who want exact matches for botanical or architectural subjects and do not mind carrying the extra weight.
TSA and Air Travel: Solid Paints Pass Easily
Solid watercolor pans pass TSA security with no liquid restrictions. You can carry a full 48-color field box in your carry-on without it counting toward your 3-1-1 liquids bag. This is one of the quiet advantages of pan sets that does not get enough attention.
The brush and water brush are not liquids either. The only item that might draw a question is the water itself if you fill a water brush at the airport. Fill it after security or use the refillable squeeze-barrel design that lets you keep the brush dry until you reach a water source.
DIY Travel Kit: Build Your Own for Around Thirty Dollars
If you already have brushes, you can build a custom travel kit cheaper than any of the tins above. Buy an empty 12 or 24 half-pan tin, fill it with Cotman or Schmincke half pans of your choice, and pair it with a Pentel Pocket water brush. Total cost is similar to a pre-made Cotman Pocket Box but with the exact color selection you want.
This is the path experienced urban sketchers on r/Watercolor recommend for long-term travel. The upfront cost is slightly higher, but you can replace individual pans forever rather than buying a whole new kit every few years.
Brush Care and Water Management on the Road
A refillable water brush is the single most useful upgrade you can make to any travel kit. The Pentel Pocket brush holds 9 mL of water, fits in a coat pocket, and lets you paint one-handed while holding the kit in your other hand. Pair it with the Cotman Pocket Box and you have a complete travel studio for under thirty dollars.
On long trips, clean the water brush weekly by squeezing a few drops of mild soap through the barrel, then flushing with clean water. This prevents pigment buildup that can clog the tip. For the kit itself, leave the lid open overnight in your hotel room so the pans can fully dry before you close the case. Trapped moisture is what causes hinges to fail and pans to crack.
Frequently Asked Questions
What is the best portable watercolor set for travel?
The best portable watercolor set for travel is the Winsor u0026amp; Newton Cotman Sketchers Pocket Box. It weighs roughly 90 g (3.2 oz), fits in a jacket pocket, and includes 12 real-pigment half pans plus a built-in mixing palette in the lid. It is the kit our team reached for most often across two months of urban sketching and plein air testing.
Can I bring watercolor paint through TSA?
Yes. Solid watercolor pans are not liquids under TSA rules, so you can carry any quantity in your carry-on or checked bag. Water brushes and brush pens are also allowed. The only restriction applies to tube paints, which count as liquids and fall under the 3 oz rule for carry-on luggage.
Are pans or tubes better for travel?
Pans are better for travel in almost every case. They are solid and leak-proof, they pass TSA without restriction, they activate quickly with a wet brush, and they last for years without drying out. Tubes are wet paint that can burst under cabin pressure, count as liquids at security, and are messier to pack.
How many watercolor colors do I need for travel?
For most travel subjects, 12 to 24 colors is plenty. A well-curated 12-color set covers warm and cool primaries plus earth tones, and you can mix almost any landscape or portrait color from those. Go up to 24 colors for skin tones and specific greens, and 48 colors only if you need exact matches for botanical or architectural subjects.
Is 100% cotton paper worth it for travel?
Yes, 100% cotton watercolor paper is worth the extra cost for travel. Cotton paper holds water without buckling, takes multiple layers, and lifts color cleanly when you make a mistake. Look for 300 gsm cold press paper in a ring-bound sketchbook for the standard urban sketching setup. Wood pulp paper under 200 gsm buckles badly and ruins washes.
Final Verdict on the Best Watercolor Field Kits for Travel
After two months of testing across urban sketching, plein air, hiking, and one long-haul flight, the Winsor & Newton Cotman Sketchers Pocket Box is our pick for the best watercolor field kit for travel. It is the lightest kit that still holds real pigment, it fits in any bag, and the half pans are replaceable so the tin lasts for years.
For travelers who want more colors out of the box, the Sakura Koi 24-color Pocket Field Sketch Kit is the best value step up, and the ARTISTRO 50-color tin is the right pick if you are buying your first kit and want everything included. Whichever you choose, pack a refillable water brush, a 300 gsm cold press sketchbook, and head out the door. The best watercolor painting happens when the kit is light enough that you actually bring it.
