Struct palette::Lch
[−]
[src]
pub struct Lch {
pub l: f32,
pub chroma: f32,
pub hue: LabHue,
pub alpha: f32,
}CIE L*C*h°, a polar version of CIE L*a*b*, with an alpha component.
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: f32
L* is the lightness of the color. 0.0 gives absolute black and 1.0 give the brightest white.
chroma: f32
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
The hue of the color, in degrees. Decides if it's red, blue, purple, etc.
alpha: f32
The transparency of the color. 0.0 is completely transparent and 1.0 is completely opaque.
