HEX to HWB Converter

How HEX to HWB conversion works

HWB (Hue, Whiteness, Blackness) is a CSS Color Module 4 color model that's designed to be more intuitive for humans to reason about than RGB. Hue is the angle on the color wheel (0–360°), just like in HSL. Whiteness is how much white is mixed into the color (0–100%), and blackness is how much black is mixed in (0–100%). Increasing both whiteness and blackness moves a color toward gray, since the two together can never exceed 100%. To convert, the hue is calculated the same way as HSL, then whiteness is derived from the minimum RGB channel value and blackness from the inverse of the maximum RGB channel value. This tool performs the conversion entirely in your browser — your colors are never sent anywhere.
