Common interface to all color representations

Required Methods

fn blend_over(self, other: Self) -> Self

Blend other color on top of this color

fn with_alpha(self, alpha: Scalar) -> Self

Override alpha component of the color

fn to_rgba(self) -> [u8; 4]

Convert color to sRGBA list

fn lerp(self, other: Self, t: f32) -> Self

Linear interpolation between self and other colors.

Provided Methods

fn to_rgb(self) -> [u8; 3]

Convert color to sRGB list (alpha is discarded)

fn luma(self) -> f32

Calculate LUMA of the color.

fn best_contrast(self, c0: Self, c1: Self) -> Self

Pick color that produces the best contrast with self
