supports-color 
Detect whether a terminal supports color
Install
$ npm install --save supports-color
Usage
var supportsColor = require('supports-color');
if (supportsColor) {
console.log('Terminal supports color');
}
It obeys the --color and --no-color CLI flags.
For situations where using --color is not possible, add an environment variable FORCE_COLOR with any value to force color. Trumps --no-color.
