Convert hexidecimal colors to RGB (red, green, blue) format. Includes support for hex shorthand '#000'

hex-to-rgb.js

function hexToRGB(hex) {
    // Strip '#'
    var nums = hex.slice(1);

    // If they pass in a shorthand hexcode convert it
    if (nums.length === 3) {
        var numStack = '';
        for (var i = 0; i < nums.length; i++) {
            numStack += nums.charAt(i) + nums.charAt(i);
        }
        nums = numStack;
    }

    // Send back converted value
    return {
        red: parseInt(nums.substring(0, 2), 16),
        green: parseInt(nums.substring(2, 4), 16),
        blue: parseInt(nums.substring(4, 6), 16)
