About RGB and HEX

RGB sets red, green and blue from 0 to 255. It describes how a screen mixes light and is written as rgb(255 87 51) in modern CSS.

HEX writes red, green and blue as two hexadecimal digits each, like #ff5733. It is the most common way to write colors on the web and in design tools.

How the conversion works

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