The universe is very big and there are many solar systems that will most likely have live and some will have complex live. Where ever the conditions are right primitive live will start to evolve such primitive live can evolve in to complex live suited to the environment of the planet on which they evolve. The colour of an alien will therefore depend on environmental factors of the given planet and its star. On earth the colour of human skin depends on the amount of UV radiation that we are exposed to this is why people from Iceland have different skin colour to someone from Africa.
