hex to RGB
Each pair of hex digits is one channel in base 16, so ff is 255 and 80 is 128.

How the conversion works
Each pair of hex digits is one channel in base 16, so ff is 255 and 80 is 128.
Both formats are computed from a single canonical representation — CIE XYZ with a D65 white point, held in floating point — rather than by chaining one format into the next. That matters because chained conversions accumulate rounding error, and because it means a colour that cannot be represented in the target format is handled deliberately rather than by accident.
When the source describes a colour outside the target's gamut, chroma is reduced in OKLCh while lightness and hue are held, following the CSS Color 4 gamut mapping algorithm. Clipping each channel independently would be simpler but visibly shifts hue on saturated colours.
