+## Usage
+
+```js
+const ansiRegex = require('ansi-regex');

+//=> true
+
+ansiRegex().test('cake');

+
+## FAQ
+
+### Why do you test for codes not in the ECMA 48 standard?
+
+Some of the codes we run as a test are codes that we acquired finding various lists of non-standard or manufacturer specific codes. We test for both standard and non-standard codes, as most of them follow the same or similar format and can be safely matched in strings without the risk of removing actual string content. There are a few non-standard control codes that do not follow the traditional format (i.e. they end in numbers) thus forcing us to exclude them from the test because we cannot reliably match them.
+
+On the historical side, those ECMA standards were established in the early 90's whereas the VT100, for example, was designed in the mid/late 70's. At that point in time, control codes were still pretty ungoverned and engineers used them for a multitude of things, namely to activate hardware ports that may have been proprietary. Somewhere else you see a similar 'anarchy' of codes is in the x86 architecture for processors; there are a ton of "interrupts" that can mean different things on certain brands of processors, most of which have been phased out.

+
+> [ANSI escape codes](http://en.wikipedia.org/wiki/ANSI_escape_code#Colors_and_Styles) for styling strings in the terminal
+
+You probably want the higher-level [chalk](https://github.com/chalk/chalk) module for styling your strings.
+
+<img src="https://cdn.rawgit.com/chalk/ansi-styles/8261697c95bf34b6c7767e2cbe9941a851d59385/screenshot.svg" width="900">
+
+
+## Install
+
+```
+$ npm install ansi-styles
+```
+
+
+## Usage
+
+```js
+const style = require('ansi-styles');
+
+console.log(`${style.green.open}Hello world!${style.green.close}`);
+
+
+// Color conversion between 16/256/truecolor
+// NOTE: If conversion goes to 16 colors or 256 colors, the original color
+//       may be degraded to fit that color palette. This means terminals
+//       that do not support 16 million colors will best-match the
+//       original color.
+console.log(style.bgColor.ansi.hsl(120, 80, 72) + 'Hello world!' + style.bgColor.close);
+console.log(style.color.ansi256.rgb(199, 20, 250) + 'Hello world!' + style.color.close);
+console.log(style.color.ansi16m.hex('#ABCDEF') + 'Hello world!' + style.color.close);
+```
+
+## API
+
+Each style has an `open` and `close` property.
+
+
+## Styles
+
+### Modifiers
+
+- `reset`
+- `bold`
+- `dim`
+- `italic` *(Not widely supported)*
+- `underline`
+- `inverse`
+- `hidden`
+- `strikethrough` *(Not widely supported)*
+
+### Colors
+
+- `black`
+- `red`
+- `green`
+- `yellow`
+- `blue`
+- `magenta`
+- `cyan`
+- `white`
+- `gray` ("bright black")
+- `redBright`
+- `greenBright`
+- `yellowBright`
+- `blueBright`
+- `magentaBright`
+- `cyanBright`
+- `whiteBright`
+
+### Background colors
+
+- `bgBlack`
+- `bgRed`
+- `bgGreen`
+- `bgYellow`
+- `bgBlue`
+- `bgMagenta`
+- `bgCyan`
+- `bgWhite`
+- `bgBlackBright`
+- `bgRedBright`
+- `bgGreenBright`
+- `bgYellowBright`
+- `bgBlueBright`
+- `bgMagentaBright`
+- `bgCyanBright`
+- `bgWhiteBright`
+
+
+## Advanced usage
+
+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.
+
+- `style.modifier`
+- `style.color`
+- `style.bgColor`
+
+###### Example
+
+```js
+console.log(style.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.
+
+###### Example
+
+```js
+console.log(style.codes.get(36));
+//=> 39
+```
+
+
+## [256 / 16 million (TrueColor) support](https://gist.github.com/XVilka/8346728)
+
+`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.
+
+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
+
+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
+
+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
+```

+</a>
+
+
+## Usage
+
+```js
+const chalk = require('chalk');
+
+console.log(chalk.blue('Hello world!'));
+```
+
+Chalk comes with an easy to use composable API where you just chain and nest the styles you want.
+
+```js
+const chalk = require('chalk');
+const log = console.log;
+
+// Combine styled and normal strings
+log(chalk.blue('Hello') + ' World' + chalk.red('!'));
+
+// Compose multiple styles using the chainable API
+log(chalk.blue.bgRed.bold('Hello world!'));
+
+// Pass in multiple arguments
+log(chalk.blue('Hello', 'World!', 'Foo', 'bar', 'biz', 'baz'));
+
+// Nest styles
+log(chalk.red('Hello', chalk.underline.bgBlue('world') + '!'));
+
+// Nest styles of the same type even (color, underline, background)
+log(chalk.green(
+	'I am a green line ' +
+	chalk.blue.underline.bold('with a blue substring') +
+	' that becomes green again!'
+));
+
+// ES2015 template literal
+log(`
+CPU: ${chalk.red('90%')}
+RAM: ${chalk.green('40%')}
+DISK: ${chalk.yellow('70%')}
+`);
+
+// ES2015 tagged template literal
+log(chalk`
+CPU: {red ${cpu.totalPercent}%}
+RAM: {green ${ram.used / ram.total * 100}%}
+DISK: {rgb(255,131,0) ${disk.used / disk.total * 100}%}
+`);
+
+// Use RGB colors in terminal emulators that support it.
+log(chalk.keyword('orange')('Yay for orange colored text!'));
+log(chalk.rgb(123, 45, 67).underline('Underlined reddish color'));
+log(chalk.hex('#DEADED').bold('Bold gray!'));
+```
+
+Easily define your own themes:
+
+```js
+const chalk = require('chalk');
+
+const error = chalk.bold.red;
+const warning = chalk.keyword('orange');
+
+console.log(error('Error!'));
+console.log(warning('Warning!'));
+```
+
+Take advantage of console.log [string substitution](https://nodejs.org/docs/latest/api/console.html#console_console_log_data_args):
+
+```js
+const name = 'Sindre';
+console.log(chalk.green('Hello %s'), name);
+//=> 'Hello Sindre'
+```
+
+
+## API
+
+### chalk.`<style>[.<style>...](string, [string...])`
+
+Example: `chalk.red.bold.underline('Hello', 'world');`
+
+Chain [styles](#styles) and call the last one as a method with a string argument. Order doesn't matter, and later styles take precedent in case of a conflict. This simply means that `chalk.red.yellow.green` is equivalent to `chalk.green`.
+
+Multiple arguments will be separated by space.
+
+### chalk.enabled
+
+Color support is automatically detected, as is the level (see `chalk.level`). However, if you'd like to simply enable/disable Chalk, you can do so via the `.enabled` property.
+
+Chalk is enabled by default unless explicitly disabled via the constructor or `chalk.level` is `0`.
+
+If you need to change this in a reusable module, create a new instance:
+
+```js
+const ctx = new chalk.constructor({enabled: false});
+```
+
+### chalk.level
+
+Color support is automatically detected, but you can override it by setting the `level` property. You should however only do this in your own code as it applies globally to all Chalk consumers.
+
+If you need to change this in a reusable module, create a new instance:
+
+```js
+const ctx = new chalk.constructor({level: 0});
+```
+
+Levels are as follows:
+
+0. All colors disabled
+1. Basic color support (16 colors)
+2. 256 color support
+3. Truecolor support (16 million colors)
+
+### chalk.supportsColor
+
+Detect whether the terminal [supports color](https://github.com/chalk/supports-color). Used internally and handled for you, but exposed for convenience.
+
+Can be overridden by the user with the flags `--color` and `--no-color`. For situations where using `--color` is not possible, add the environment variable `FORCE_COLOR=1` to forcefully enable color or `FORCE_COLOR=0` to forcefully disable. The use of `FORCE_COLOR` overrides all other color support checks.
+
+Explicit 256/Truecolor mode can be enabled using the `--color=256` and `--color=16m` flags, respectively.

+
+## Tagged template literal
+
+Chalk can be used as a [tagged template literal](http://exploringjs.com/es6/ch_template-literals.html#_tagged-template-literals).
+
+```js
+const chalk = require('chalk');
+
+const miles = 18;
+const calculateFeet = miles => miles * 5280;
+
+console.log(chalk`
+  There are {bold 5280 feet} in a mile.
+  In {bold ${miles} miles}, there are {green.bold ${calculateFeet(miles)} feet}.
+`);
+```
+
+Blocks are delimited by an opening curly brace (`{`), a style, some content, and a closing curly brace (`}`).
+
+Template styles are chained exactly like normal Chalk styles. The following two statements are equivalent:
+
+```js
+console.log(chalk.bold.rgb(10, 100, 200)('Hello!'));
+console.log(chalk`{bold.rgb(10,100,200) Hello!}`);
+```
+
+Note that function styles (`rgb()`, `hsl()`, `keyword()`, etc.) may not contain spaces between parameters.
+
+All interpolated values (`` chalk`${foo}` ``) are converted to strings via the `.toString()` method. All curly braces (`{` and `}`) in interpolated value strings are escaped.
+
+
+## 256 and Truecolor color support
+
+Chalk supports 256 colors and [Truecolor](https://gist.github.com/XVilka/8346728) (16 million colors) on supported terminal apps.
+
+Colors are downsampled from 16 million RGB values to an ANSI color format that is supported by the terminal emulator (or by specifying `{level: n}` as a Chalk option). For example, Chalk configured to run at level 1 (basic color support) will downsample an RGB value of #FF0000 (red) to 31 (ANSI escape for red).
+
+Examples:
+
+- `chalk.hex('#DEADED').underline('Hello, world!')`
+- `chalk.keyword('orange')('Some orange text')`
+- `chalk.rgb(15, 100, 204).inverse('Hello!')`
+
+Background versions of these models are prefixed with `bg` and the first level of the module capitalized (e.g. `keyword` for foreground colors and `bgKeyword` for background colors).
+
+- `chalk.bgHex('#DEADED').underline('Hello, world!')`
+- `chalk.bgKeyword('orange')('Some orange text')`
+- `chalk.bgRgb(15, 100, 204).inverse('Hello!')`
+
+The following color models can be used:
+
+- [`rgb`](https://en.wikipedia.org/wiki/RGB_color_model) - Example: `chalk.rgb(255, 136, 0).bold('Orange!')`
+- [`hex`](https://en.wikipedia.org/wiki/Web_colors#Hex_triplet) - Example: `chalk.hex('#FF8800').bold('Orange!')`
+- [`keyword`](https://www.w3.org/wiki/CSS/Properties/color/keywords) (CSS keywords) - Example: `chalk.keyword('orange').bold('Orange!')`
+- [`hsl`](https://en.wikipedia.org/wiki/HSL_and_HSV) - Example: `chalk.hsl(32, 100, 50).bold('Orange!')`
+- [`hsv`](https://en.wikipedia.org/wiki/HSL_and_HSV) - Example: `chalk.hsv(32, 100, 100).bold('Orange!')`
+- [`hwb`](https://en.wikipedia.org/wiki/HWB_color_model)  - Example: `chalk.hwb(32, 0, 50).bold('Orange!')`
+- `ansi16`
+- `ansi256`
+
+
+## Windows
+
+If you're on Windows, do yourself a favor and use [`cmder`](http://cmder.net/) instead of `cmd.exe`.
+
+
+## Origin story
+
+[colors.js](https://github.com/Marak/colors.js) used to be the most popular string styling module, but it has serious deficiencies like extending `String.prototype` which causes all kinds of [problems](https://github.com/yeoman/yo/issues/68) and the package is unmaintained. Although there are other packages, they either do too much or not enough. Chalk is a clean and focused alternative.

+
+## Installation
+
+```sh
+$ yarn add pretty-format
+```
+
+## Usage
+
+```js
+const prettyFormat = require('pretty-format'); // CommonJS
+```
+
+```js
+import prettyFormat from 'pretty-format'; // ES2015 modules
+```
+
+```js
+const val = {object: {}};
+val.circularReference = val;
+val[Symbol('foo')] = 'foo';
+val.map = new Map([['prop', 'value']]);
+val.array = [-0, Infinity, NaN];
+
+console.log(prettyFormat(val));
+/*
+Object {
+  "array": Array [
+    -0,
+    Infinity,
+    NaN,
+  ],
+  "circularReference": [Circular],
+  "map": Map {
+    "prop" => "value",
+  },
+  "object": Object {},
+  Symbol(foo): "foo",
+}
+*/
+```
+
+## Usage with options
+
+```js
+function onClick() {}
+
+console.log(prettyFormat(onClick));
+/*
+[Function onClick]
+*/
+
+const options = {
+  printFunctionName: false,
+};
+console.log(prettyFormat(onClick, options));
+/*
+[Function]
+*/
+```

+
+Property values of `theme` are from
+[ansi-styles colors](https://github.com/chalk/ansi-styles#colors)
+
+```js
+const DEFAULT_THEME = {
+  comment: 'gray',
+  content: 'reset',
+  prop: 'yellow',
+  tag: 'cyan',
+  value: 'green',
+};
+```
+
+## Usage with plugins
+
+The `pretty-format` package provides some built-in plugins, including:
+
+* `ReactElement` for elements from `react`
+* `ReactTestComponent` for test objects from `react-test-renderer`
+
+```js
+// CommonJS
+const prettyFormat = require('pretty-format');
+const ReactElement = prettyFormat.plugins.ReactElement;
+const ReactTestComponent = prettyFormat.plugins.ReactTestComponent;
+
+const React = require('react');
+const renderer = require('react-test-renderer');
+```
+
+```js
+// ES2015 modules and destructuring assignment
+import prettyFormat from 'pretty-format';
+const {ReactElement, ReactTestComponent} = prettyFormat.plugins;
+
+import React from 'react';
+import renderer from 'react-test-renderer';
+```
+
+```js
+const onClick = () => {};
+const element = React.createElement('button', {onClick}, 'Hello World');
+
+const formatted1 = prettyFormat(element, {
+  plugins: [ReactElement],
+  printFunctionName: false,
+});
+const formatted2 = prettyFormat(renderer.create(element).toJSON(), {
+  plugins: [ReactTestComponent],
+  printFunctionName: false,
+});
+/*
+<button
+  onClick=[Function]
+>
+  Hello World
+</button>
+*/
+```
+
+## Usage in Jest
+
+For snapshot tests, Jest uses `pretty-format` with options that include some of
+its built-in plugins. For this purpose, plugins are also known as **snapshot
+serializers**.
+
+To serialize application-specific data types, you can add modules to
+`devDependencies` of a project, and then:
+
+In an **individual** test file, you can add a module as follows. It precedes any
+modules from Jest configuration.
+
+```js
+import serializer from 'my-serializer-module';
+expect.addSnapshotSerializer(serializer);
+
+// tests which have `expect(value).toMatchSnapshot()` assertions
+```
+
+For **all** test files, you can specify modules in Jest configuration. They
+precede built-in plugins for React, HTML, and Immutable.js data types. For
+example, in a `package.json` file:
+
+```json
+{
+  "jest": {
+    "snapshotSerializers": ["my-serializer-module"]
+  }
+}
+```
+
+## Writing plugins
+
+A plugin is a JavaScript object.
+
+If `options` has a `plugins` array: for the first plugin whose `test(val)`
+method returns a truthy value, then `prettyFormat(val, options)` returns the
+result from either:
+
+* `serialize(val, …)` method of the **improved** interface (available in
+  **version 21** or later)
+* `print(val, …)` method of the **original** interface (if plugin does not have
+  `serialize` method)
+
+### test
+
+Write `test` so it can receive `val` argument of any type. To serialize
+**objects** which have certain properties, then a guarded expression like
+`val != null && …` or more concise `val && …` prevents the following errors:
+
+* `TypeError: Cannot read property 'whatever' of null`
+* `TypeError: Cannot read property 'whatever' of undefined`
+
+For example, `test` method of built-in `ReactElement` plugin:
+
+```js
+const elementSymbol = Symbol.for('react.element');
+const test = val => val && val.$$typeof === elementSymbol;
+```
+
+Pay attention to efficiency in `test` because `pretty-format` calls it often.
+
+### serialize
+
+The **improved** interface is available in **version 21** or later.
+
+Write `serialize` to return a string, given the arguments:
+
+* `val` which “passed the test”
+* unchanging `config` object: derived from `options`
+* current `indentation` string: concatenate to `indent` from `config`
+* current `depth` number: compare to `maxDepth` from `config`
+* current `refs` array: find circular references in objects
+* `printer` callback function: serialize children
+
+### config
+
+| key                 | type      | description                                             |
+| :------------------ | :-------- | :------------------------------------------------------ |
+| `callToJSON`        | `boolean` | call `toJSON` method (if it exists) on objects          |
+| `colors`            | `Object`  | escape codes for colors to highlight syntax             |
+| `escapeRegex`       | `boolean` | escape special characters in regular expressions        |
+| `indent`            | `string`  | spaces in each level of indentation                     |
+| `maxDepth`          | `number`  | levels to print in arrays, objects, elements, and so on |
+| `min`               | `boolean` | minimize added space: no indentation nor line breaks    |
+| `plugins`           | `array`   | plugins to serialize application-specific data types    |
+| `printFunctionName` | `boolean` | include or omit the name of a function                  |
+| `spacingInner`      | `strong`  | spacing to separate items in a list                     |
+| `spacingOuter`      | `strong`  | spacing to enclose a list of items                      |
+
+Each property of `colors` in `config` corresponds to a property of `theme` in
+`options`:
+
+* the key is the same (for example, `tag`)
+* the value in `colors` is a object with `open` and `close` properties whose
+  values are escape codes from
+  [ansi-styles](https://github.com/chalk/ansi-styles) for the color value in
+  `theme` (for example, `'cyan'`)
+
+Some properties in `config` are derived from `min` in `options`:
+
+* `spacingInner` and `spacingOuter` are **newline** if `min` is `false`
+* `spacingInner` is **space** and `spacingOuter` is **empty string** if `min` is
+  `true`
+
+### Example of serialize and test
+
+This plugin is a pattern you can apply to serialize composite data types. Of
+course, `pretty-format` does not need a plugin to serialize arrays :)
+
+```js
+// We reused more code when we factored out a function for child items
+// that is independent of depth, name, and enclosing punctuation (see below).
+const SEPARATOR = ',';
+function serializeItems(items, config, indentation, depth, refs, printer) {
+  if (items.length === 0) {
+    return '';
+  }
+  const indentationItems = indentation + config.indent;
+  return (
+    config.spacingOuter +
+    items
+      .map(
+        item =>
+          indentationItems +
+          printer(item, config, indentationItems, depth, refs), // callback
+      )
+      .join(SEPARATOR + config.spacingInner) +
+    (config.min ? '' : SEPARATOR) + // following the last item
+    config.spacingOuter +
+    indentation
+  );
+}
+
+const plugin = {
+  test(val) {
+    return Array.isArray(val);
+  },
+  serialize(array, config, indentation, depth, refs, printer) {
+    const name = array.constructor.name;
+    return ++depth > config.maxDepth
+      ? '[' + name + ']'
+      : (config.min ? '' : name + ' ') +
+          '[' +
+          serializeItems(array, config, indentation, depth, refs, printer) +
+          ']';
+  },
+};
+```
+
+```js
+const val = {
+  filter: 'completed',
+  items: [
+    {
+      text: 'Write test',
+      completed: true,
+    },
+    {
+      text: 'Write serialize',
+      completed: true,
+    },
+  ],
+};
+```
+
+```js
+console.log(
+  prettyFormat(val, {
+    plugins: [plugin],
+  }),
+);
+/*

+  "filter": "completed",
+  "items": Array [

+    Object {
+      "completed": true,
+      "text": "Write serialize",
+    },
+  ],
+}
+*/
+```
+
+```js
+console.log(
+  prettyFormat(val, {
+    indent: 4,
+    plugins: [plugin],

+        },
+        Object {
+            "completed": true,
+            "text": "Write serialize",
+        },
+    ],
+}
+*/
+```
+
+```js
+console.log(
+  prettyFormat(val, {
+    maxDepth: 1,
+    plugins: [plugin],
+  }),
+);
+/*
+Object {
+  "filter": "completed",
+  "items": [Array],
+}
+*/
+```
+
+```js
+console.log(
+  prettyFormat(val, {
+    min: true,
+    plugins: [plugin],
+  }),
+);
+/*
+{"filter": "completed", "items": [{"completed": true, "text": "Write test"}, {"completed": true, "text": "Write serialize"}]}
+*/
+```
+
+### print
+
+The **original** interface is adequate for plugins:
+
+* that **do not** depend on options other than `highlight` or `min`
+* that **do not** depend on `depth` or `refs` in recursive traversal, and
+* if values either
+  * do **not** require indentation, or
+  * do **not** occur as children of JavaScript data structures (for example,
+    array)
+
+Write `print` to return a string, given the arguments:
+
+* `val` which “passed the test”
+* current `printer(valChild)` callback function: serialize children
+* current `indenter(lines)` callback function: indent lines at the next level
+* unchanging `config` object: derived from `options`
+* unchanging `colors` object: derived from `options`
+
+The 3 properties of `config` are `min` in `options` and:
+
+* `spacing` and `edgeSpacing` are **newline** if `min` is `false`
+* `spacing` is **space** and `edgeSpacing` is **empty string** if `min` is
+  `true`
+
+Each property of `colors` corresponds to a property of `theme` in `options`:
+
+* the key is the same (for example, `tag`)
+* the value in `colors` is a object with `open` and `close` properties whose
+  values are escape codes from
+  [ansi-styles](https://github.com/chalk/ansi-styles) for the color value in
+  `theme` (for example, `'cyan'`)
+
+### Example of print and test
+
+This plugin prints functions with the **number of named arguments** excluding
+rest argument.
+
+```js
+const plugin = {
+  print(val) {
+    return `[Function ${val.name || 'anonymous'} ${val.length}]`;
+  },
+  test(val) {
+    return typeof val === 'function';
+  },
+};
+```
+
+```js
+const val = {
+  onClick(event) {},
+  render() {},
+};
+
+prettyFormat(val, {
+  plugins: [plugin],
+});
+/*
+Object {
+  "onClick": [Function onClick 1],
+  "render": [Function render 0],
+}
+*/
+
+prettyFormat(val);
+/*
+Object {
+  "onClick": [Function onClick],
+  "render": [Function render],
+}
+*/
+```
+
+This plugin **ignores** the `printFunctionName` option. That limitation of the
+original `print` interface is a reason to use the improved `serialize`
+interface, described above.
+
+```js
+prettyFormat(val, {
+  plugins: [pluginOld],
+  printFunctionName: false,
+});
+/*
+Object {
+  "onClick": [Function onClick 1],
+  "render": [Function render 0],
+}
+*/
+
+prettyFormat(val, {
+  printFunctionName: false,
+});
+/*
+Object {
+  "onClick": [Function],
+  "render": [Function],
+}
+*/
+```

+# supports-color [![Build Status](https://travis-ci.org/chalk/supports-color.svg?branch=master)](https://travis-ci.org/chalk/supports-color)
+
+> Detect whether a terminal supports color
+
+
+## Install
+
+```
+$ npm install supports-color
+```
+
+
+## Usage
+
+```js
+const supportsColor = require('supports-color');
+
+if (supportsColor.stdout) {
+	console.log('Terminal stdout supports color');
+}
+
+if (supportsColor.stdout.has256) {
+	console.log('Terminal stdout supports 256 colors');
+}
+
+if (supportsColor.stderr.has16m) {
+	console.log('Terminal stderr supports 16 million colors (truecolor)');
+}
+```
+
+
+## API
+
+Returns an `Object` with a `stdout` and `stderr` property for testing either streams. Each property is an `Object`, or `false` if color is not supported.
+
+The `stdout`/`stderr` objects specifies a level of support for color through a `.level` property and a corresponding flag:
+
+- `.level = 1` and `.hasBasic = true`: Basic color support (16 colors)
+- `.level = 2` and `.has256 = true`: 256 color support
+- `.level = 3` and `.has16m = true`: Truecolor support (16 million colors)
+
+
+## Info
+
+It obeys the `--color` and `--no-color` CLI flags.
+
+Can be overridden by the user with the flags `--color` and `--no-color`. For situations where using `--color` is not possible, add the environment variable `FORCE_COLOR=1` to forcefully enable color or `FORCE_COLOR=0` to forcefully disable. The use of `FORCE_COLOR` overrides all other color support checks.
+
+Explicit 256/Truecolor mode can be enabled using the `--color=256` and `--color=16m` flags, respectively.
