[Watchmen] Why does Dr. Manhattan have to stay blue? Why doesn't he go back to how he looked before the accident?

I mean if he can zap a mark on his forehead, change his size, teleport to mars, change color, have omniscient knowledge of the universe, and duplicate himself what's stopping him from going back to how he used to be? Why would he want to be blue?

He doesn't want to? 

He has transcended human needs and wants, after the accident this is what he became. What he is.

Who exactly would he be changing for? He certainly doesn't care about such trivial things.
