Struct palette::Hsl [−] [src]

pub struct Hsl {
    pub hue: RgbHue,
    pub saturation: f32,
    pub lightness: f32,
    pub alpha: f32,
}

Linear HSL color space with an alpha component.

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

hue: RgbHue

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

saturation: f32

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

lightness: f32

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.

alpha: f32

The transparency of the color. 0.0 is completely transparent and 1.0 is completely opaque.
