A Rust library for converting between color spaces and comparing colors, ported from https://github.com/berendeanicolae/ColorSpace.
You can convert between any supported color spaces using the from trait method:
rust
let rgb = Rgb::new(0.0, 255.0, 0.0);
let hsv = Hsv::from(rgb);
assert_eq!(hsv, Hsv::new(120.0, 1.0, 1.0));
You can also do this generically with the from_color method:
rust
let rgb = Rgb::new(0.0, 0.0, 255.0);
let hsv = Hsv::from_color(&rgb);
assert_eq!(hsv, Hsv::new(240.0, 1.0, 1.0));
You can compare colors by using the compare_* methods:
rust
let rgb = Rgb::new(255.0, 0.0, 0.0);
let hsv = Hsv::new(0.0, 1.0, 1.0);
let diff = rgb.compare_cie2000(&hsv);
assert_eq!(diff, 0.0);
// these two colors are the same, so the difference is zero
