A bit late but better late than never:
function invert(rgb) {
rgb = Array.prototype.join.call(arguments).match(/(-?[0-9.]+)/g);
for (var i = 0; i < rgb.length; i++) {
rgb[i] = (i === 3 ? 1 : 255) - rgb[i];
}
return rgb;
}
console.log(
invert('rgba(255, 0, 0, 0.3)'), // 0, 255, 255, 0.7
invert('rgb(255, 0, 0)'), // 0, 255, 255
invert('255, 0, 0'), // 0, 255, 255
invert(255, 0, 0) // 0, 255, 255
);
