Color palette

Extracts dominant colors: 2–16 hues sorted by area share.

Extracts a palette of dominant colors from an image. The algorithm is Median Cut (Heckbert, 1982) — recursive RGB-space partitioning into balanced clusters. Pick a color count from 2 to 16. Each swatch shows its HEX value and the percent of image area it covers. Click a swatch to copy the HEX. Runs in the browser.
