Struct palette::Hsl [] [src]

pub struct Hsl<Wp = D65, T = f32> where
    T: Float,
    Wp: WhitePoint<T>, 
{ pub hue: RgbHue<T>, pub saturation: T, pub lightness: T, pub white_point: PhantomData<Wp>, }

Linear HSL color space.

The HSL color space can be seen as a cylindrical version of RGB, where the hue is the angle around the color cylinder, the saturation is the distance from the center, and the lightness is the height from the bottom. Its composition makes it especially good for operations like changing green to red, making a color more gray, or making it darker.

See HSV for a very similar color space, with brightness instead of lightness.

Fields

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

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

Decides how light the color will look. 0.0 will be black, 0.5 will give a clear color, and 1.0 will give white.

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