How to Set Up a Watercolor Palette
The way you organize your palette matters more than most beginners expect. I changed my layout once, three years into painting, and immediately got fewer muddy mixes. Not because I learned new technique — just because warm and cool colors stopped ending up next to each other on the mixing surface.

What You'll Need
- A watercolor palette with at least 12 wells (24 recommended)
- Watercolor paints (pan or tube — both work)
- A small spray bottle filled with clean water
- Paper towels or a cloth for cleaning
- A reference card or notebook for color notes

Step-by-Step Setup Guide
Decide: travel or studio
This determines everything else. A travel palette (plastic, under 300g) should hold 12–16 colors — more than that and it stops being portable. A studio palette (ceramic, 24+ wells) can hold your full color range and doesn't need to close securely because it stays on your desk.
Pro Tip: If you're not sure which you need, start with a 24-well plastic palette. It's a reasonable middle ground while you figure out how and where you paint.
Separate warm from cool
Put warm colors (warm yellow, warm red, warm blue) along one edge and cool colors (cool yellow, cool red, cool blue) along the other. When you're mixing, you always reach in the right direction. I got fewer muddy mixes after switching to this layout than from any other change I made.
Pro Tip: Leave 2–3 empty wells on each side. You'll find colors you want to add within the first month.
Load the paint
Tube paint: squeeze it into the well until it's slightly mounded over the rim — paint shrinks 30–40% as it dries. Let it dry 24–48 hours before painting. Pan paint: press the pan into the well. It should click in with light pressure. Don't mix very different brands in adjacent wells; the binder strength varies and it affects how the colors rewet.
Pro Tip: Dried tube paint in a palette behaves exactly like pan paint. Don't feel like you need to use it wet.
Record pigment codes, not color names
Tape a reference card to the inside of the lid with the pigment codes (PB29, PY150, PR108, etc.) rather than brand names. A 'Cobalt Blue' from Holbein and one from Winsor & Newton share the same pigment code but behave differently. When you run out and need to replace a color, the code is the only reliable way to find a match.
Pro Tip: Take a photo of your filled palette before closing it for the first time. Future you will thank you.
Mist before each session
Ten minutes before painting, spray the wells lightly with clean water. Dried paint that's been softened for 10 minutes takes one brush stroke to pick up. Dried paint that hasn't been pre-wetted takes five to ten. That delay breaks your flow constantly, especially in wet-into-wet work where timing matters.
Pro Tip: Get a small spray bottle and keep it next to your palette. It costs under $2 and saves a lot of frustration.
Keep the mixing area clean
Leave the paint wells alone between sessions — dried watercolor rewets fine. Wipe the mixing area down at the end of each session with a damp cloth. Once the mixing surface gets grey and contaminated, everything you mix comes out dull. This is the part most beginners skip, and it's the reason most beginners think they're mixing wrong when they're just painting on a dirty surface.
Pro Tip: If you're getting muddy mixes and can't figure out why, clean your mixing area first. It's usually that.
Popular Color Layout Strategies
Warm/cool split
The layout most working watercolorists use. Warm colors on one side, cool on the other, earths at the ends where they don't contaminate primaries.
Y → Y-O → O → R-O → R → R-V | V → B-V → B → B-G → G → Y-G | Earths
Limited palette (6 colors)
The best way to actually learn to mix. Fewer colors means you have to figure out how to get what you need rather than reaching for a convenience color.
Hansa Yellow Light · Quinacridone Red · Phthalo Blue (GS) · Raw Sienna · Burnt Umber · Ivory Black
Split primary
Used by artists who want the widest possible mixing range. Two versions of each primary — one warm, one cool. Requires 12+ wells to do properly.
Warm Yellow · Cool Yellow · Warm Red · Cool Red · Warm Blue · Cool Blue + earth tones
Need a palette first?
None of this matters if your palette itself is fighting you. I use a 24-well ceramic for my desk and a Sakura Koi when I'm out. I’ve tested 15+ options — here are the ones worth buying:
