-
-Conversions and data for color spaces. [Demo](http://colorjs.github.io/color-space).
-
-
-## Usage
-
-[](https://npmjs.org/package/color-space/)
-
-```js
-var space = require('color-space');
-
-//convert lab to lch
-var result = space.lab.lch([80,50,60]);
-```
-
-You can require a separate space to reduce size significantly:
-
-```js
-var rgb = require('color-space/rgb');
-var hsl = require('color-space/hsl');
-
-//convert rgb to hsl
-rgb.hsl([200,230,100]);
-```
