Struct Hwb

#[repr(C)]
pub struct Hwb<S = Srgb, T = f32> {
    pub hue: RgbHue<T>,
    pub whiteness: T,
    pub blackness: T,
    pub standard: PhantomData<S>,
}

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.

HWB component values are typically real numbers (such as floats), but may also be converted to and from u8 for storage and interoperability purposes. The hue is then within the range [0, 255].

use approx::assert_relative_eq;
use palette::Hwb;

let hwb_u8 = Hwb::new_srgb(128u8, 85, 51);
let hwb_f32 = hwb_u8.into_format::<f32>();

assert_relative_eq!(hwb_f32, Hwb::new(180.0, 1.0 / 3.0, 0.2));

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

standard: PhantomData<S>

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

Implementations
