HWB (short for Hue-Whiteness-Blackness) is another method of specifying sRGB colors, similar to HSL, but often even easier for humans to work with. It describes colors with a starting hue, then a degree of whiteness and blackness to mix into that base hue. https://drafts.csswg.org/css-color/#the-hwb-notation
