Expand description

CIE L*C*uv h°uv, a polar version of CIE L*u*v*.

L*C*uv h°uv shares its range and perceptual uniformity with L*u*v*, 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: T

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

chroma: T

C*uv is the colorfulness of the color. It’s similar to saturation. 0.0 gives gray scale colors, and numbers around 130-180 gives fully saturated colors, depending on the hue. The upper limit of 180 should include the whole L*u*v*.

hue: LuvHue<T>

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

white_point: PhantomData<Wp>

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