Use the color wheel to control hue and whiteness, or use the bars. ->HWB is a way to describe color, where >H is hue, with values from 0-360, >W is how much white you add, from 0-1, and >B is how much black you add, also from 0-1 Have Fun!
HWB is a fairly interesting concept. It is designed to be a more intuitive color model than HSL or HSV, so I decided to show it off here. H: Hue, like in HSB and HSL. W: Whiteness. Think of it as mixing white paint in with the color in various amounts. B: Blackness. Think of it as mixing black paint in with the color in various amounts.
