Struct bevy_color::prelude::Hsla
source · pub struct Hsla {
pub hue: f32,
pub saturation: f32,
pub lightness: f32,
pub alpha: f32,
}
Expand description
Color in Hue-Saturation-Lightness (HSL) color space with alpha. Further information on this color model can be found on Wikipedia.
§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.
Fields§
§hue: f32
The hue channel. [0.0, 360.0]
saturation: f32
The saturation channel. [0.0, 1.0]
lightness: f32
The lightness channel. [0.0, 1.0]
alpha: f32
The alpha channel. [0.0, 1.0]
Implementations§
source§impl Hsla
impl Hsla
sourcepub const fn with_saturation(self, saturation: f32) -> Self
pub const fn with_saturation(self, saturation: f32) -> Self
Return a copy of this color with the saturation channel set to the given value.
sourcepub const fn with_lightness(self, lightness: f32) -> Self
pub const fn with_lightness(self, lightness: f32) -> Self
Return a copy of this color with the lightness channel set to the given value.
sourcepub fn sequential_dispersed(index: u32) -> Self
pub fn sequential_dispersed(index: u32) -> Self
Generate a deterministic but quasi-randomly distributed
color from a provided index
.
This can be helpful for generating debug colors.
§Examples
// Unique color for an entity
// let entity_index = entity.index();
let color = Hsla::sequential_dispersed(entity_index);
// Palette with 5 distinct hues
let palette = (0..5).map(Hsla::sequential_dispersed).collect::<Vec<_>>();

should be between 0.0 and 1.0.
The amount represents an absolute decrease in luminance, and is distributive:
color.darker(a).darker(b) == color.darker(a + b)
. Colors are clamped to black
if the amount would cause them to go below black. Read moresource§fn lighter(&self, amount: f32) -> Self
