Struct palette::Luma [] [src]

pub struct Luma<Wp = D65, T = f32> where
    T: Float,
    Wp: WhitePoint<T>, 
{ pub luma: T, pub white_point: PhantomData<Wp>, }

Linear luminance.

Luma is a purely gray scale color space, which is included more for completeness than anything else, and represents how bright a color is perceived to be. It's basically the Y component of CIE XYZ. The lack of any form of hue representation limits the set of operations that can be performed on it.

Fields

The lightness of the color. 0.0 is black and 1.0 is white.

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