Kuretake Gansai Tambi 12-Color
Kuretake's 12-color mini set contains the same full-pan pigments as their 36-color set, just in a smaller tin. The colors are specifically chosen for maximum mixing range — two yellows, two reds, two blues, a green, a purple, a brown, a black, and a warm grey. You can mix almost anything from these 12. The tin fits in a shirt pocket.
- ✓Same quality as full Gansai Tambi set
- ✓12 colors well-chosen for mixing
- ✓True pocket size
- ✓Full pans (not half)
- ✓Premium pigments
Winsor & Newton Cotman Mini Set 8-Color
The Cotman mini tin is the smallest Cotman product — 8 half-pans in a tin the size of a business card case. The mixing palette on the lid is tiny, but it exists. The paint quality is the same reliable Cotman you'd find in any of their products. For under $15 you get a complete kit that fits in a small pocket.
- ✓Cotman quality
- ✓Business-card size
- ✓Lid mixing palette
- ✓Refillable half-pans
- ✓Very affordable
Sakura Koi 12-Color Travel Set
The Sakura Koi 12-Color Travel Set is smaller than their 24-color field set, with a slimmer tin designed specifically for bullet journalists and sketchbookers. The 12 colors reactivate fast and the tin has a slot for the included water brush pen. For daily carry and journaling use, this is the most practical mini set.
- ✓Slot for water brush pen
- ✓Slim for journaling use
- ✓Fast reactivation
- ✓Good color selection
- ✓Daily-carry designed
Himi 36-Color Mini Cup Set
The Himi mini cup set packs 36 press-fit jelly cups into a small round tin. It's not premium paint, but 36 colors in a tin this small is remarkable. Works best as a first set for journaling or for someone who wants variety without the commitment of a full set.
- ✓36 colors in tiny form factor
- ✓Very cheap
- ✓Fun for beginners
- ✓Portable round tin
Pocket Palette Custom Set (DIY)
The most popular mini setup among serious painters isn't a commercial product — it's a Bijou Box or small metal tin filled with hand-picked half-pans from your preferred brands. You pick Holbein for the colors you use most, Daniel Smith for granulating effects, and Cotman for the rest. Costs more upfront but the result is a mini set that matches your personal palette exactly.
- ✓You choose every color
- ✓Mix brands to optimize
- ✓Can include artist-grade colors
- ✓Fully customizable
- ✓Scales with your needs
How We Tested
All five sets were used daily for 4 weeks as the only painting tool carried — no other kit. Evaluated for fit in a jeans pocket, reactivation speed first thing in the morning, whether the mixing area was usable for practical color mixing, and how the pans held up after 20+ open-close cycles. The custom DIY option was assembled using a Bijou Box tin with a mix of Holbein and Daniel Smith half-pans.
Buying Guide
When Is a Mini Set Better Than a Full Set?
A mini set wins when weight and space matter more than versatility. Commuting, hiking, journaling at a cafe, travel sketching in cities. A full travel set like the Sakura Koi 24-color is already quite compact — the mini category makes sense when even that is too much to carry. If you're choosing between a mini set and staying home, the mini set wins every time.
8 Colors vs 12 Colors vs 24 Colors: Which Mini Size Makes Sense?
8 colors is enough for monochromatic studies and limited palette work, but feels restrictive for anything representational. 12 colors hits the sweet spot — enough for a warm and cool of each primary plus a few earth tones and a black. 24 colors is no longer mini, it's a travel set. For daily carry, 12 is the practical number most painters converge on.
Building a Custom Mini Palette vs Buying a Ready-Made Mini Set
A custom tin pays off if you already have tube paints and know your preferred colors. You'll spend about $5 on a small tin or box, $10 on a set of empty half-pans, and then fill them with artist-grade paint from tubes. The result is a mini palette worth $80 in components for much less than buying those same colors in a commercial set. The Kuretake Gansai Tambi is the best ready-made option for painters who don't want the DIY hassle.

Frequently Asked Questions
What is the smallest watercolor set worth buying?
The Winsor & Newton Cotman Mini 8-color at $12 is the smallest complete set that uses paint worth using. It fits in a jeans pocket, the lid doubles as a mixing surface, and the Cotman formula is reliable. Below this price point you're looking at sets where the paint quality actively fights you.
Are mini watercolor sets good for travel?
Yes, for the right kind of travel. Mini sets are ideal for urban sketching, travel journaling, and day hikes where every gram counts. They're not ideal for multi-hour painting sessions or large-format work where you need more mixing space and paint volume. Most dedicated outdoor painters eventually graduate to a proper travel set like the Sakura Koi 24-color or Cotman Field Box.
Can you do serious watercolor painting with a mini set?
With the Kuretake Gansai Tambi 12-color or a custom DIY tin with artist-grade paints, yes. The limiting factor isn't the pan count but the mixing space. The Gansai Tambi tin has no built-in mixing palette — you need a small separate palette card. With that added, the 12 colors cover most painting needs for A5-sized work.
What mini watercolor set do professional urban sketchers use?
Most professional urban sketchers build their own custom tin using a Winsor & Newton Bijou Box or similar small metal tin filled with half-pans of artist-grade paint. The Holbein and Daniel Smith colors in a custom tin represent the typical high-end approach. The Kuretake Gansai Tambi 12-color is the most common ready-made alternative that professionals actually recommend.
