- -## Types - -**Colord** is written in strict TypeScript and ships with types in the library itself — 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. - -```ts -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 }; // ERROR -``` - -
