Impasto - Paint Recipes
Color Mixing Made Simple
Free · Designed for iPad. Not verified for macOS.
Painters know the frustration: you see a color you want, but mixing it from your tubes is guesswork. Impasto turns that into a precise recipe.
Take a photo of your reference — a landscape, a still life, a fabric swatch — and tap the color you want. Impasto gives you the exact mixing recipe using Kubelka-Munk spectral color science at 36 wavelengths. This is not simple RGB blending; it models how light interacts with real pigments and paint layers, the same physics used in professional color matching.
You get pigment names, ratios, and an accuracy percentage. For example: "3x Burnt Umber + 1x Yellow Ochre + 1x Titanium White — 99% match." Save recipes to reference while you paint.
Customize your palette to match the tubes you actually own.
Includes an AI Paint Expert for questions about color theory, technique, and pigments.
Works with oil, acrylic, watercolor, and gouache. Built for physical painters who care about accuracy.
Fixed pigment submissions so new colors are saved reliably. Added Williamsburg Montserrat Orange to the palette. Updated Paint Expert with a newer model and usage limits.
