oklch-color-science-gap-in-frontend-taste

Our frontend-taste skill uses hex/hsl color representations throughout. Impeccable’s engine is OKLCH-first — it handles oklch, oklab, lch, and lab color spaces natively for perceptually uniform color operations. This is a capability gap: OKLCH produces better contrast ratios, more accurate lightness perception, and is the modern CSS Color Level 4 standard. All new frontend color work should adopt OKLCH-first.
