Rust library for converting RGB colors to the CIE-L*a*b* color space

extern crate lab;
use lab::Lab;

let pink_in_lab = Lab::from_rgb(&[253, 120, 138]);
// Lab  { l: 66.6348, a: 52.260696, b: 14.850557 }

extern crate lab;
extern crate image;

use lab::Lab;
use image::Rgba;

let pixel: Rgba<u8> = Rgba { data: [253, 120, 138, 255] };
let lab = Lab::from_rgba(&pixel.data);
// Lab  { l: 66.6348, a: 52.260696, b: 14.850557 }
