Struct palette::Lch
[−]
[src]
pub struct Lch<T: Float = f32> { pub l: T, pub chroma: T, pub hue: LabHue<T>, }
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: T
L* is the lightness of the color. 0.0 gives absolute black and 1.0 give the brightest white.
chroma: T
C* is the colorfulness of the color. It's similar to saturation. 0.0
gives gray scale colors, and numbers around 1.0-1.41421356 gives fully
saturated colors. The upper limit of 1.41421356 (or sqrt(2.0)
) should
include the whole L*a*b* space and some more.
hue: LabHue<T>
The hue of the color, in degrees. Decides if it's red, blue, purple, etc.
