supports-color Build Status

Detect whether a terminal supports color


$ npm install supports-color


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)');


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:


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.
