Struct palette::Hwb
[−]
[src]
pub struct Hwb<S = Srgb, T = f32> where
T: 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.
