Struct palette::Hsv [−] [src]

pub struct Hsv {
    pub hue: RgbHue,
    pub saturation: f32,
    pub value: f32,
    pub alpha: f32,
}

Linear HSV color space with an alpha component.

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

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.

value: f32

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.

alpha: f32

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