Mix
Add 1–4 paints from the palette, or try a classic neutral:
Ultramarine + Burnt Sienna · watercolour grey
More water → lighter wash. Paper is your lightest value.
High body covers the ground; lower body acts more like a glaze.
Harmonies
Screens average RGB; paint absorbs light — that’s why blue + yellow is green here.

Paint library
Search all brands · find dupes

Dupe matching uses ΔE (CIE76) in Lab across same-medium brand lines. Approximate planning hues — confirm against real swatches.
Mixing decks
Recipes · charts · match a colour or photo
Themed cards, each a ready-made recipe across five mediums. Every swatch is mixed by the pigment engine — tap a card to load its paints, ratios and water/white/black into the mixer, then tweak.
Pick two pigments to see the whole range of mixes between them — from pure A to pure B. Tap any step to load it.
Swatches shown at ~35% water. Two-pigment mixes stay cleaner than three.
Every paint in a set mixed against every other — the chart watercolourists paint by hand from a pan set. The diagonal is pure pigment; each row runs that pigment against the whole palette. Tap any cell to load it.
Granulation, separation and staining aren’t modelled — real paint-outs will bloom and settle where these cells sit flat. Print the blank template to paint your own alongside.
Sample a colour straight off an image, then reverse-plan a mix for it from your palette. A photo is often the fastest way in — match what you can see.
