API
Color parsing
colord(input)
Parses the given input and creates a new Colord instance. String parsing strictly conforms to CSS Color Level Specifications .
import { colord } from "colord" ;
colord ("#FFF" );
colord ("#ffffff" );
colord ("#ffffffff" );
colord ("rgb(255, 255, 255)" );
colord ("rgba(255, 255, 255, 0.5)" );
colord ("rgba(100% 100% 100% / 50%)" );
colord ("hsl(90, 100%, 100%)" );
colord ("hsla(90, 100%, 100%, 0.5)" );
colord ("hsla(90deg 100% 100% / 50%)" );
colord ("tomato" );
colord ({ r : 255 , g : 255 , b : 255 });
colord ({ r : 255 , g : 255 , b : 255 , a : 1 });
colord ({ h : 360 , s : 100 , l : 100 });
colord ({ h : 360 , s : 100 , l : 100 , a : 1 });
colord ({ h : 360 , s : 100 , v : 100 });
colord ({ h : 360 , s : 100 , v : 100 , a : 1 });
Check out the "Plugins" section for more input format examples.
getFormat(input)
Returns a color model name for the input passed to the function. Uses the same parsing system as colord

Types
Colord is written in strict TypeScript and ships with types in the library itself ā no need for any other install. We provide everything you need in one tiny package.
While not only typing its own functions and variables, Colord can also help you type yours. Depending on the color space you are using, you can also import and use the type that is associated with it.
import { RgbColor , RgbaColor , HslColor , HslaColor , HsvColor , HsvaColor } from "colord" ;
const foo : HslColor = { h : 0 , s : 0 , l : 0 };
const bar : RgbColor = { r : 0 , g : 0 , v : 0 };
