About HWB and HSB / HSV
HWB describes a color by its hue plus how much white and black are mixed in. It is part of CSS Color 4 and is handy for tints and shades.
HSV, also called HSB, uses hue, saturation and value. Photoshop, Figma and most color pickers use it for the square picker.
How the conversion works
We read the HWB value, convert it to CIE XYZ with the matrices from the CSS Color 4 specification and then into HSB / HSV. Values outside the target gamut are mapped by the CSS Color 4 algorithm, which keeps lightness and hue and reduces chroma.
