- # 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.
