Usually image color reduction is done in two independent phases: first a color quantization algorithm finds a palette, which is then used by a pixel mapping phase to assign every output pixel a color from the palette. Ignoring any possible dithering for now, the chosen palette color is the one with the shortest Euclidean distance to the original pixel color. But if we know both the old and new colors for each pixel, it’s possible to refine the palette.

nutelch — cusp explorer
NUTELCH measures chroma relative to the gamut shell — the cusp — in OKLCH and LCH. You ask for a fraction of the way to the boundary (relC) instead of an absolute chroma, so “saturation” means the same thing at every lightness and hue and never accidentally lands out of gamut, while the result stays a native oklch() / lch() color. It's dependency-free and LUT-backed: the boundaries are precomputed, so lookups are fast. nutelch on GitHub →
