By default, you get a map of styles, but the styles are also available as groups. They are non-enumerable so they don't show up unless you access them explicitly. This makes it easier to expose only a subset in a higher-level module.

###### Example
```js
console.log(style.color.green.open);
import styles from 'ansi-styles';
console.log(styles.color.green.open);
```
Raw escape codes (i.e. without the CSI escape prefix `\u001B[` and render mode postfix `m`) are available under `style.codes`, which returns a `Map` with the open codes as keys and close codes as values.

## 16 / 256 / 16 million (TrueColor) support
`ansi-styles` uses the [`color-convert`](https://github.com/Qix-/color-convert) package to allow for converting between various colors and ANSI escapes, with support for 256 and 16 million colors.
`ansi-styles` allows converting between various color formats and ANSI escapes, with support for 16, 256 and [16 million colors](https://gist.github.com/XVilka/8346728).

- `hex`
- `keyword`
- `hsl`
- `hsv`
- `hwb`
- `ansi`
- `ansi256`
- `ansi`
To use these, call the associated conversion function with the intended output, for example:
```js
style.color.ansi.rgb(100, 200, 15); // RGB to 16 color ansi foreground code
style.bgColor.ansi.rgb(100, 200, 15); // RGB to 16 color ansi background code
import styles from 'ansi-styles';
style.color.ansi256.hsl(120, 100, 60); // HSL to 256 color ansi foreground code
style.bgColor.ansi256.hsl(120, 100, 60); // HSL to 256 color ansi foreground code
styles.color.ansi(styles.rgbToAnsi(100, 200, 15)); // RGB to 16 color ansi foreground code
styles.bgColor.ansi(styles.hexToAnsi('#C0FFEE')); // HEX to 16 color ansi foreground code
style.color.ansi16m.hex('#C0FFEE'); // Hex (RGB) to 16 million color foreground code
style.bgColor.ansi16m.hex('#C0FFEE'); // Hex (RGB) to 16 million color background code
styles.color.ansi256(styles.rgbToAnsi256(100, 200, 15)); // RGB to 256 color ansi foreground code
styles.bgColor.ansi256(styles.hexToAnsi256('#C0FFEE')); // HEX to 256 color ansi foreground code
styles.color.ansi16m(100, 200, 15); // RGB to 16 million color foreground code
styles.bgColor.ansi16m(...styles.hexToRgb('#C0FFEE')); // Hex (RGB) to 16 million color foreground code
```

# 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).
