Struct palette::Lab [−] [src]

pub struct Lab<T: Float = f32> {
    pub l: T,
    pub a: T,
    pub b: T,
}

The CIE L*a*b* (CIELAB) color space.

CIE L*a*b* is a device independent color space which includes all perceivable colors. It's sometimes used to convert between other color spaces, because of its ability to represent all of their colors, and sometimes in color manipulation, because of its perceptual uniformity. This means that the perceptual difference between two colors is equal to their numerical difference.

The parameters of L*a*b* are quite different, compared to many other color spaces, so manipulating them manually can be unintuitive.

Fields

l: T

L* is the lightness of the color. 0.0 gives absolute black and 1.0 give the brightest white.

a: T

a* goes from red at -1.0 to green at 1.0.

b: T

b* goes from yellow at -1.0 to blue at 1.0.
