About CMYK and OKLab

CMYK is cyan, magenta, yellow and key (black) ink in percent. The conversion here is the simple device-independent formula, so for print always check with your printer profile.

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.

How the conversion works

We read the CMYK value, convert it to CIE XYZ with the matrices from the CSS Color 4 specification and then into OKLab. Values outside the target gamut are mapped by the CSS Color 4 algorithm, which keeps lightness and hue and reduces chroma.
