OKLCH Color Picker and Converter
Pick colors in OKLCH by perceptual lightness, chroma, and hue, with the sRGB result in every format.
oklch(0.700 0.150 250.0) → #4ba3f7 · inside sRGB
#4ba3f7
OKLab/OKLCH is the same implementation the converter ships: one math, two doors. Inputs are perceptual coordinates; every output is anchored to what an sRGB display can show.
