Features & Capabilities

A focused, distraction-free tool for exploring color. Browse expertly curated palettes, build your own from scratch, pull colors directly from a photo, or just swipe your way through endless variations.

EXPLORE Swipe down to load a new palette at random. Swipe up to go back. Swipe left or right to cycle through layout variants — same colors, different proportions.

800+ palettes are organized by mood: warm, cool, vibrant, neutral, and dark. Filter by mood, source, or number of colors, then lock in a column count to keep that size as you browse.

CREATE Three ways to build a palette:

Generate -- pick a base color and apply a color theory scheme: Complementary, Analogous, Triadic, Split-Complementary, Tetradic, or Monochromatic. See a live preview, name it, and save or apply with a tap.

Manual -- pick each color individually with your own color pickers. Build exactly what you have in mind.

Photo -- take a photo or choose one from your library. Dominant colors are extracted automatically and assembled into a palette proportional to how much of the image each color occupies.

COLLECT Like any palette with the heart button to keep track of favorites. Save palettes for quick access. Tap any color swatch at any time to copy its hex code to your clipboard.

All your created and saved palettes live in one place, filterable by liked or all.

REARRANGE Press and hold any color, then drag it onto another to swap them. The palette rearranges and saves automatically.

EVERY COLOR, INSTANTLY Tap any color swatch to copy its hex code. Hex and RGB values are shown directly on every color — no digging required.

AMBIENT Press and hold the menu button to enter Ambient mode. Palettes auto-cycle every few seconds, each with a fresh layout, every label hidden — just pure color. Tap anywhere to exit. Perfect on a phone propped on your desk, or an old iPad turned into a slow-rotating mood board.

ALSO ON MAC A Book of Colors is also available on the Mac App Store — a menu bar app with keyboard shortcuts, drag-to-reorder, and a fullscreen Ambient mode.
