Struct palette::Lch [] [src]

pub struct Lch<Wp = D65, T: Float = f32> where
    T: Float,
    Wp: WhitePoint<T>, 
{ pub l: T, pub chroma: T, pub hue: LabHue<T>, pub white_point: PhantomData<Wp>, }

CIE L*C*h°, a polar version of CIE L*a*b*.

L*C*h° shares its range and perceptual uniformity with L*a*b*, but it's a cylindrical color space, like HSL and HSV. This gives it the same ability to directly change the hue and colorfulness of a color, while preserving other visual aspects.

Fields

L* is the lightness of the color. 0.0 gives absolute black and 100.0 gives the brightest white.

C* is the colorfulness of the color. It's similar to saturation. 0.0 gives gray scale colors, and numbers around 128-181 gives fully saturated colors. The upper limit of 128 should include the whole L*a*b* space and some more.

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

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