Struct bevy::color::Laba

``````pub struct Laba {
pub lightness: f32,
pub a: f32,
pub b: f32,
pub alpha: f32,
}``````
Expand description

Color in LAB color space, with alpha

§Conversion

Conversion between the various color spaces is achieved using Rust’s native From trait. Because certain color spaces are defined by their transformation to and from another space, these From implementations reflect that set of definitions.

``````let color = Srgba::rgb(0.5, 0.5, 0.5);

// Using From explicitly
let linear_color = LinearRgba::from(color);

// Using Into
let linear_color: LinearRgba = color.into();``````

For example, the sRGB space is defined by its relationship with Linear RGB, and HWB by its with sRGB. As such, it is the responsibility of sRGB to provide From implementations for Linear RGB, and HWB for sRGB. To then provide conversion between Linear RGB and HWB directly, HWB is responsible for implementing these conversions, delegating to sRGB as an intermediatory. This ensures that all conversions take the shortest path between any two spaces, and limit the proliferation of domain specific knowledge for each color space to their respective definitions.
