GAMUT_EPSILON

Shared floating-point margin for gamut boundary checks.

constimport { GAMUT_EPSILON } from '@pbroom/color-kit';constants.ts:13
const GAMUT_EPSILON = 0.000075;

Matrix math through OKLab can produce near-zero negative linear channel values for colors that are actually in gamut. Every gamut membership or margin classification should use this single tolerance so boundary behavior stays consistent across modules.

inSrgbGamut / inP3Gamut apply it to gamma-encoded channels (matching CSS Color 4 and colorjs.io inGamut), i.e. linear bounds of [-GAMUT_EPSILON / 12.92, linearize(1 + GAMUT_EPSILON)].
