Struct Oklcha

pub struct Oklcha {
    pub lightness: f32,
    pub chroma: f32,
    pub hue: f32,
    pub alpha: f32,
}

Color in Oklch 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.

Implementations

impl Oklcha

pub const fn new(lightness: f32, chroma: f32, hue: f32, alpha: f32) -> Oklcha

Construct a new Oklcha color from components.

Arguments

• lightness - Lightness channel. [0.0, 1.0]
• chroma - Chroma channel. [0.0, 1.0]
• hue - Hue channel. [0.0, 360.0]
• alpha - Alpha channel. [0.0, 1.0]

pub const fn lch(lightness: f32, chroma: f32, hue: f32) -> Oklcha

Construct a new Oklcha color from (l, c, h) components, with the default alpha (1.0).

Arguments

• lightness - Lightness channel. [0.0, 1.0]
• chroma - Chroma channel. [0.0, 1.0]
• hue - Hue channel. [0.0, 360.0]
• alpha - Alpha channel. [0.0, 1.0]

pub const fn with_lightness(self, lightness: f32) -> Oklcha

Return a copy of this color with the ‘lightness’ channel set to the given value.

let color = Oklcha::sequential_dispersed(entity_index);

// Palette with 5 distinct hues
let palette = (0..5).map(Oklcha::sequential_dispersed).collect::<Vec<_>>();
