+# 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
+import convert from 'color-convert';
+
+convert.rgb.hsl(140, 200, 100);             // [96, 48, 59]
+convert.keyword.rgb('blue');                // [0, 0, 255]
+
+const rgbChannels = convert.rgb.channels;     // 3
+const cmykChannels = convert.cmyk.channels;   // 4
+const ansiChannels = convert.ansi16.channels; // 1
+```
+
+# Install
+
+```sh
+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
+import convert from '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
+import convert from '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).
+
+## Color Space Scales
+Conversions rely on an agreed upon 'full-scale' value for each of the channels. Listed here are those values for the most common color spaces
+
+### rgb
+channel | full-scale value
+---|---
+r | 255
+g | 255
+b | 255
+
+### hsl
+channel | full-scale value
+---|---
+h | 360
+s | 100
+l | 100
+
+### hsv
+channel | full-scale value
+---|---
+h | 360
+s | 100
+v | 100
+
+### hwb
+channel | full-scale value
+---|---
+h | 360
+w | 100
+b | 100
+
+### xyz
+channel | full-scale value
+---|---
+x | 94
+y | 99
+z | 108
+
+### lab
+channel | full-scale value
+---|---
+l | 100
+a | -86, 98
+b | -108, 94
+
+### lch
+channel | full-scale value
+---|---
+l | 100
+c | 133
+h | 360
+
+### oklab
+channel | full-scale value
+---|---
+l | 100
+a | -23, 28
+b | -31, 20
+
+### oklch
+channel | full-scale value
+---|---
+l | 100
+c | 32
+h | 360
+
+### cmyk
+channel | full-scale value
+---|---
+c | 100
+m | 100
+y | 100
+k | 100
+
+### hex
+channel | full-scale value
+---|---
+hex | ```0xffffff```
+
+### keyword
+channel | value
+---|---
+name | any key from [color-name](https://github.com/colorjs/color-name/blob/master/index.js)
+
+### apple
+channel | full-scale value
+---|---
+0 | 65535
+1 | 65535
+2 | 65535
+
+### gray
+channel | full-scale value
+---|---
+gray | 100
