Color Expert

This is a serious color science reference packed into 286K words covering OKLCH/OKLAB perceptual color spaces, palette generation algorithms, WCAG contrast checking, color naming systems, and pigment mixing theory. You'd reach for this when building design systems, generating accessible color palettes, or need to explain why certain color combinations work or fail contrast requirements. The inclusion of historical color theory alongside modern perceptual models like OKLCH makes it useful for both technical implementation and explaining color concepts to designers. Curated by @meodai, who maintains several color tools in the open source ecosystem, so the reference material leans practical rather than academic.
