Build Status

Color-convert is a color conversion library for JavaScript and node. It converts all ways between rgb, hsl, hsv, hwb, cmyk, ansi, ansi16 and CSS keywords:

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

converter.rgb(140, 200, 100).hsl()   // [96, 48, 59]

converter.keyword("blue").rgb()      // [0, 0, 255]


$ npm install color-convert


Color-convert exports a converter object with getter/setter methods for each color space. It caches conversions:

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

converter.rgb(140, 200, 100).hsl()   // [96, 48, 59]

converter.rgb([140, 200, 100])       // args can be an array

Plain functions

Get direct conversion functions with no fancy objects:

require("color-convert").rgb2hsl([140, 200, 100]);   // [96, 48, 59]


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

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


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])

Other spaces

There are some conversions from rgb (sRGB) to XYZ and LAB too, available as rgb2xyz(), rgb2lab(), xyz2rgb(), and xyz2lab().


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.

Something went wrong with that request. Please try again.
