# Color-space [](https://github.com/colorjs/color-space/actions/workflows/test.yml) [](http://github.com/badges/stability-badges) [](https://npmjs.org/color-space) [](https://bundlephobia.com/package/color-space)
Open collection of color spaces.
[Demo](http://colorjs.github.io/color-space).
## Usage
```js
import space from 'color-space';
//convert lab to lch
var result = space.lab.lch([80,50,60]);
```
Spaces can be imported separately:
```js
import rgb from 'color-space/rgb.js';
import hsl from 'color-space/hsl.js';
//convert rgb to hsl
rgb.hsl([200, 230, 100]);
```
## API
```js
.(array);
.name //space name
.channel //channel names
.min //channel minimums
.max //channel maximums
```

## Purpose
A complete collection of color spaces with minimal consistent and clean API, verified formulas and cases.
While alternatives focus on digital color spaces, this project takes broader perspective, including historical / multidisciplinary spaces.
A side effect is verifying and correcting papers.
