Color-space

Conversions and data for color spaces. Demo.

Usage

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:

var rgb = require('color-space/rgb');
var hsl = require('color-space/hsl');

//convert rgb to hsl
rgb.hsl([200,230,100]);

API

<fromSpace>.<toSpace>(array);
<space>.name //space name
<space>.min //channel minimums
<space>.max //channel maximums
<space>.channel //channel names
<space>.alias //alias space names

Contribute

Please fork, add color space with basic conversions to/from XYZ or RGB and tests. The goal of project is to provide the most complete set of color spaces with maximally minimal uniform API.
