color-convert

Color-convert is a library of plain color conversion functions. It converts between rgb, hsl, hsv, and cmyk:

colorConvert.rgb2hsl([140, 200, 100]));   // [96, 48, 59]

Install

node

For node with npm:

npm install color-convert

browser

Download the latest color-convert.js. All the methods are on the colorConvert object.

API

Color-convert converts all ways between rgb, hsl, hsv, cmyk, and CSS keyword. Also from rgb to xyz and lab (these two assume sRGB color profile):

var convert = require("color-convert");

convert.rgb2hsl([255, 255, 255])        // rgb -> hsl, hsv, cmyk, keyword, xyz, and lab

convert.hsl2rgb([360, 100, 100])        // hsl -> rgb, hsv, cmyk, and keyword

convert.hsv2rgb([360, 100, 100])        // hsv -> rgb, hsl, cmyk, and keyword

convert.cmyk2rgb([100, 100, 100, 100])  // cmyk -> rgb, hsl, hsv, and keyword

convert.keyword2rgb("blue")             // keyword -> rgb, hsl, hsv, and cmyk

convert.xyz2rgb([100, 100, 100])        // xyz -> rgb

Unrounded

To get the unrounded conversion, append Raw to the function name:

colorConvert.rgb2hslRaw([140, 200, 100]);   // [95.99999999999999, 47.619047619047606, 58.82352941176471]

Hash

There's also a hash of the conversion functions keyed first by the "from" color space, then by the "to" color space:

convert["hsl"]["hsv"]([160, 0, 20]) == convert.hsl2hsv([160, 0, 20])

Contribute

Please fork, add conversions, figure out color profile stuff for XYZ, LAB, etc. This is meant to be a basic library that can be used by other libraries to wrap color calculations in some cool way.
