+
+> 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.
+
+For situations where using `--color` is not possible, use the environment variable `FORCE_COLOR=1` (level 1), `FORCE_COLOR=2` (level 2), or `FORCE_COLOR=3` (level 3) 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.
