Struct palette::Hwb

#[repr(C)]
pub struct Hwb<S = Srgb, T = f32> where
    T: Component + Float,
    S: RgbSpace,  {
    pub hue: RgbHue<T>,
    pub whiteness: T,
    pub blackness: T,
    pub space: PhantomData<S>,
}

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

hue: RgbHue<T>

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

whiteness: T

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.

blackness: T

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

space: PhantomData<S>

The white point and RGB primaries this color is adapted to. The default is the sRGB standard.
