HSL to RGB:

/**
     * Converts an HSL color value to RGB. Conversion formula
     * adapted from http://en.wikipedia.org/wiki/HSL_color_space.
     * Assumes h, s, and l are contained in the set [0, 1] and
     * returns r, g, and b in the set [0, 255].
     *
     * @param   {number}  h       The hue
     * @param   {number}  s       The saturation
     * @param   {number}  l       The lightness
     * @return  {Array}           The RGB representation
     */
    function hslToRgb(h, s, l){
        var r, g, b;

        if(s == 0){
            r = g = b = l; // achromatic
        }else{
            var hue2rgb = function hue2rgb(p, q, t){
                if(t < 0) t += 1;
                if(t > 1) t -= 1;
                if(t < 1/6) return p + (q - p) * 6 * t;
                if(t < 1/2) return q;
                if(t < 2/3) return p + (q - p) * (2/3 - t) * 6;
                return p;
            }

            var q = l < 0.5 ? l * (1 + s) : l + s - l * s;
            var p = 2 * l - q;
            r = hue2rgb(p, q, h + 1/3);
            g = hue2rgb(p, q, h);
            b = hue2rgb(p, q, h - 1/3);
        }

        return [Math.round(r * 255), Math.round(g * 255), Math.round(b * 255)];
    }
