# color-convert [](https://travis-ci.org/Qix-/color-convert) Color-convert is a color conversion library for JavaScript and node. It converts all ways between `rgb`, `hsl`, `hsv`, `hwb`, `cmyk`, `ansi`, `ansi16`, `hex` strings, and CSS `keyword`s (will round to closest): ```js var convert = require('color-convert'); convert.rgb.hsl(140, 200, 100); // [96, 48, 59] convert.keyword.rgb('blue'); // [0, 0, 255] var rgbChannels = convert.rgb.channels; // 3 var cmykChannels = convert.cmyk.channels; // 4 var ansiChannels = convert.ansi16.channels; // 1 ``` # Install ```console $ npm install color-convert ``` # API Simply get the property of the _from_ and _to_ conversion that you're looking for. All functions have a rounded and unrounded variant. By default, return values are rounded. To get the unrounded (raw) results, simply tack on `.raw` to the function. All 'from' functions have a hidden property called `.channels` that indicates the number of channels the function expects (not including alpha). ```js var convert = require('color-convert'); // Hex to LAB convert.hex.lab('DEADBF'); // [ 76, 21, -2 ] convert.hex.lab.raw('DEADBF'); // [ 75.56213190997677, 20.653827952644754, -2.290532499330533 ] // RGB to CMYK convert.rgb.cmyk(167, 255, 4); // [ 35, 0, 98, 0 ] convert.rgb.cmyk.raw(167, 255, 4); // [ 34.509803921568626, 0, 98.43137254901961, 0 ] ``` ### Arrays All functions that accept multiple arguments also support passing an array. Note that this does **not** apply to functions that convert from a color that only requires one value (e.g. `keyword`, `ansi256`, `hex`, etc.) ```js var convert = require('color-convert'); convert.rgb.hex(123, 45, 67); // '7B2D43' convert.rgb.hex([123, 45, 67]); // '7B2D43' ``` ## Routing Conversions that don't have an _explicitly_ defined conversion (in [conversions.js](conversions.js)), but can be converted by means of sub-conversions (e.g. XYZ -> **RGB** -> CMYK), are automatically routed together. This allows just about any color model supported by `color-convert` to be converted to any other model, so long as a sub-conversion path exists. This is also true for conversions requiring more than one step in between (e.g. LCH -> **LAB** -> **XYZ** -> **RGB** -> Hex). Keep in mind that extensive conversions _may_ result in a loss of precision, and exist only to be complete. For a list of "direct" (single-step) conversions, see [conversions.js](conversions.js). # Contribute If there is a new model you would like to support, or want to add a direct conversion between two existing models, please send us a pull request. # License Copyright © 2011-2016, Heather Arthur and Josh Junon.
