Calculate Lighter Shade of RGB

function getRGB(color) {

    if (result = /rgb(s*([0-9]{1,3})s*,s*([0-9]{1,3})s*,s*([0-9]{1,3})s*)/.exec(color)) return [parseInt(result[1]), parseInt(result[2]), parseInt(result[3])];

    if (result = /#([a-fA-F0-9]{2})([a-fA-F0-9]{2})([a-fA-F0-9]{2})/.exec(color)) return [parseInt(result[1], 16), parseInt(result[2], 16), parseInt(result[3], 16)];

    if (result = /#([a-fA-F0-9])([a-fA-F0-9])([a-fA-F0-9])/.exec(color)) return [parseInt(result[1] + result[1], 16), parseInt(result[2] + result[2], 16), parseInt(result[3] + result[3], 16)];

    for(var i = 0; i < rgb.length; i++){
