HWB to HSLA examples
About HWB and HSLA
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.
HSLA is HSL plus an alpha channel for opacity, written as hsla(11, 100%, 60%, 0.5). Alpha goes from 0 (fully transparent) to 1 (fully opaque), and modern CSS also accepts it inside hsl().
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 HSLA. Values outside the target gamut are mapped by the CSS Color 4 algorithm, which keeps lightness and hue and reduces chroma.
