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.
