Struct amethyst_rendy::palette::Hsv

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

Linear HSV color space.

HSV is a cylindrical version of RGB and it's very similar to HSL. The difference is that the value component in HSV determines the brightness of the color, and not the lightness. The difference is that, for example, red (100% R, 0% G, 0% B) and white (100% R, 100% G, 100% B) has the same brightness (or value), but not the same lightness.

Fields

hue: RgbHue<T>

The hue of the color, in degrees. Decides if it's red, blue, purple, etc.

saturation: T

The colorfulness of the color. 0.0 gives gray scale colors and 1.0 will give absolutely clear colors.

value: T

Decides how bright the color will look. 0.0 will be black, and 1.0 will give a bright an clear color that goes towards white when saturation goes towards 0.0.

space: PhantomData<S>

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