Struct Color 

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

An RGBA colour with components in 0.0..=1.0.

Every painter call takes impl Into<Color>, so a plain [r, g, b, a] array works as well as a Color.

Components are sRGB, the values a color picker or CSS shows: Color::hex(0x2a3550) puts exactly #2a3550 on screen, on sprites, shapes, circles, text, meshes and the clear color alike. The renderer decodes them to linear for blending, so blends and the per-vertex gradients of filled shapes mix in sRGB, as CSS does.

Fields

r: f32

g: f32

b: f32

a: f32

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

Opaque colour from a 0xRRGGBB literal, as in CSS: Color::hex(0xff8800).

pub const fn hex_rgba(rgba: u32) -> Color

Colour from a 0xRRGGBBAA literal: Color::hex_rgba(0xff880080) is half-transparent.
