About OKLab and LCH
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.
CIE LCH is Lab in polar form: lightness, chroma and hue. It is easier to reason about than Lab and is supported in CSS as lch().
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 LCH. Values outside the target gamut are mapped by the CSS Color 4 algorithm, which keeps lightness and hue and reduces chroma.
