Struct Luv

#[repr(C)]
pub struct Luv {
    pub l: f32,
    pub u: f32,
    pub v: f32,
}

Struct representing a color in CIE LUV, a.k.a. L*u*v*, color space

Fields

l: f32

The L* value (achromatic luminance) of the colour in 0–100 range.

u: f32

The u* value of the colour.

Together with v* value, it defines chromaticity of the colour. The u* coordinate represents colour’s position on red-green axis with negative values indicating more red and positive more green colour. Typical values are in -134–220 range (but exact range for ‘valid’ colours depends on luminance and v* value).

v: f32

The u* value of the colour.

Together with u* value, it defines chromaticity of the colour. The v* coordinate represents colour’s position on blue-yellow axis with negative values indicating more blue and positive more yellow colour. Typical values are in -140–122 range (but exact range for ‘valid’ colours depends on luminance and u* value).
