The blue dominance was based initially on the misconception that the suit was blue. Which of course evolved in the the suit of the early fifties and then the "new look" from 1954.
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.
