+# color-convert
+
+[![Build Status](https://travis-ci.org/Qix-/color-convert.svg?branch=master)](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.

+
+> [Swizzle](https://en.wikipedia.org/wiki/Swizzling_(computer_graphics)) your function arguments; pass in mixed arrays/values and get a clean array
+
+## Usage
+
+```js
+var swizzle = require('simple-swizzle');
+
+function myFunc() {
+	var args = swizzle(arguments);
+	// ...
+	return args;
+}
+
+myFunc(1, [2, 3], 4); // [1, 2, 3, 4]
+myFunc(1, 2, 3, 4);   // [1, 2, 3, 4]
+myFunc([1, 2, 3, 4]); // [1, 2, 3, 4]
+```
+
+Functions can also be wrapped to automatically swizzle arguments and be passed
+the resulting array.
+
+```js
+var swizzle = require('simple-swizzle');
+
+var swizzledFn = swizzle.wrap(function (args) {
+	// ...
+	return args;
+});
+
+swizzledFn(1, [2, 3], 4); // [1, 2, 3, 4]
+swizzledFn(1, 2, 3, 4);   // [1, 2, 3, 4]
+swizzledFn([1, 2, 3, 4]); // [1, 2, 3, 4]
