The suit, in its final form ('tec #33 and onwards iirc) was supposed to be black. That is what I meant. Just like Superman had been depicted with Roman sandals for a time during his debut doesn't mean it should happen on screen.
But what Im saying I know that the original suit is supposed to be black. Even after the fact Batman was/is drawn with the blue suit as well as the black. There's a difference between that and your Superman reference because Superman isn't drawn with the sandals anymore while Batman is still drawn in the blue suit.
