Struct Color 

pub struct Color {
    pub r: f32,
    pub g: f32,
    pub b: f32,
    pub a: f32,
}

An sRGB color with straight alpha, each channel in 0.0..=1.0.

Fields

r: f32

g: f32

b: f32

a: f32

Implementations

impl Color

pub const fn hex(rgb: u32) -> Self

An opaque color from 0xRRGGBB.

pub const fn hexa(rgba: u32) -> Self

A color from 0xRRGGBBAA.

pub const fn alpha(self, alpha: f32) -> Self

The same color at alpha opacity.

pub fn blend(self, to: Self, t: f32) -> Self

Linear interpolation toward to; t is clamped to 0.0..=1.0, and the ends are exact.

State layers, tonal containers and palette transitions all use this one blend, so a hovered selected control resolves over its current container instead of stacking translucent fills.

pub fn luminance(self) -> f32

Relative luminance (WCAG 2.x / sRGB): Rec. 709 weights on the linearized channels, so mid gray #808080 is about 0.216, not 0.5.
