About OKLab and OKLCH
OKLab is a modern perceptual color space from 2020. Equal steps look equal to the eye, which makes gradients and mixes cleaner than in RGB or HSL.
OKLCH is OKLab in polar form: lightness, chroma and hue. Tailwind CSS v4 uses it for its whole palette because changing lightness keeps the hue stable.
How the conversion works
We read the OKLab value, convert it to CIE XYZ with the matrices from the CSS Color 4 specification and then into OKLCH. Values outside the target gamut are mapped by the CSS Color 4 algorithm, which keeps lightness and hue and reduces chroma.
