About OKLCH and LCH
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.
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 OKLCH 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.
