Struct palette::Hwb [] [src]

pub struct Hwb<Wp = D65, T = f32> where
    T: Float,
    Wp: WhitePoint<T>, 
{ pub hue: RgbHue<T>, pub whiteness: T, pub blackness: T, pub white_point: PhantomData<Wp>, }

Linear HWB color space.

HWB is a cylindrical version of RGB and it's very closely related to HSV. It describes colors with a starting hue, then a degree of whiteness and blackness to mix into that base hue.

It is very intuitive for humans to use and many color-pickers are based on the HWB color system

Fields

The hue of the color, in degrees. Decides if it's red, blue, purple, etc. Same as the hue for HSL and HSV.

The whiteness of the color. It specifies the amount white to mix into the hue. It varies from 0 to 1, with 1 being always full white and 0 always being the color shade (a mixture of a pure hue with black) chosen with the other two controls.

The blackness of the color. It specifies the amount black to mix into the hue. It varies from 0 to 1, with 1 being always full black and 0 always being the color tint (a mixture of a pure hue with white) chosen with the other two

The white point associated with the color's illuminant and observer. D65 for 2 degree observer is used by default.
