Open Source Software
A free, open-source iOS app for painters learning color theory — built with SwiftUI, powered by real subtractive RYB pigment mixing.
Color Mixer
An interactive color wheel where you pick any two colors by dragging on the wheel and adjusting brightness. The app mixes them using a subtractive RYB algorithm — the same color model painters have used for centuries — so the results feel true to life on canvas, not like screen pixels.
Choose your medium and watch how the mix changes:
-
Oil — pure 50/50 pigment blend, the most accurate
-
Acrylic — slight darkening, because acrylics shift as they dry
-
Watercolor — transparency simulation, diluting toward white the way water thins paint
Paint Palatte
A curated library of 23 named artist pigments.
Tap any two colors, and the Mixing Bench at the bottom shows you the blended result along with a harmony note — whether the two colors are analogous, complementary, near-complementary, or something in between. Great for discovering how to mix your paints together to match your natural landscape in Plein Air Painting.

The color wheel — primaries, secondaries, tertiaries
-
Mixing concepts — complementary pairs, analogous harmony, warm vs. cool, tints and shades
