A Book of Colors

Color, organized.

For years I've worked in two rooms: one full of canvases, one full of screens. This app is the door between them — palettes curated the way a painter sees color, built the way a designer expects a tool to feel.

Hundreds of palettes, sorted by feel

I organized these by mood — warm, cool, vibrant, neutral, dark. Swipe up for a new palette, down to go back. Tap any color to copy its hex code. Save the ones that stick.

Palettes from my paintings

One package is drawn directly from my canvases — colors I've actually mixed, lived with, and painted with. The Starter Kit adds 600+ more. New packages arrive over time; the app checks automatically.

Built from color theory

I built in six harmony schemes: Complementary, Analogous, Triadic, Split-Complementary, Tetradic, and Monochromatic. Pick any base color and the palette generates instantly. Apply it or save it.

Pull colors from anything

I use this myself — point at a painting, a room, a sunset. The app extracts dominant colors using k-means clustering. Any image becomes a palette you can use or save.

Ready for your workflow

Every palette exports as a 1080×1080 image with hex and RGB labels, written straight to your Photos library — ready for moodboards, Figma files, or your camera roll.
