Convert a colour between hex, RGB, HSL, OKLCH, CMYK, and CSS names, and derive complementary, analogous, triadic, split-complementary and monochromatic harmonies. Harmonies are rotated in OKLCH, not HSL, so they keep their perceived lightness instead of one looking washed out. Reports WCAG contrast against white and black, and flags colours clipped to fit sRGB.

WHY DELEGATE THIS: Colour-space arithmetic has no feedback signal — a wrong hex-to-OKLCH looks exactly like a right one until someone sees the colour. Harmonies rotated in HSL also come out perceptually unbalanced, which is the usual mistake.
