I've said this before, and I'll say it again.

I cannot envision superman as anyone other than a light skinned man with straight, black hair, with a side part.

That's been his design for nearly three times as long as I've existed.

I wouldn't make him blonde, I wouldn't make him ginger, I wouldn't make him asian, I wouldn't shave his head. I would not change any essential element of his visual design, because there's simply no need to. Doing so at this point is not reimaging superman, it's putting an impostor in his place.
