# 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.
