I can see them going with the black costume upon his initial rebirth, then as he gains his powers back it transitions into the traditional colors. It would be a good way to tribute the 90s comics while not dwelling on it.
Audience complaint: The colors of Superman's costume are too dark and muted.
Snyder/D.C. response: Black costume, bitches!
According to Screen Rant it's from the Justice League set:

I also watched the video at that link, which contains a long comment by Deborah Snyder about the criticism of the dark tone of MoS and BvS. She really just doesn't get it.
The other argument I have against Snyder's notion that people don't like to see their heroes deconstructed is this: you have to construct something before you can deconstruct it. But with only one previous Superman movie in this series, and no previous Batman movie, there hasn't been any time to build up the characters in the first place. It wants the payoff from having years of emotional investment, but hasn't put the time in. My screenwriting professor used to say "Show, don't tell" all the time, but this movie spends a lot of time telling us things instead of showing us - by necessity, since there aren't previous films in the series for this to be building on. To me, one of the biggest examples of this flaw is the portrayal of Batman as a man over the edge who will kill (directly or indirectly) - the movie tells us that Batman has lost himself in the fight, asking us to fill in the gaps of imagining this Batman as both a noble crime fighter and a man who's lost his way, but the movie doesn't actually show us any of that.
I think this is a key to how someone like myself can be totally fine with the deconstruction while someone like yourself can't. I've seen 12 other movies with Superman and Batman since 1978, not counting Man of Steel. TWELVE. I feel zero need to have more films show me what I can essentially glean from those other films re: how Batman and Superman are in the context of "normal" story positioning. I don't want to spend time on that again, therefore I'm totally fine with keeping that context external to the film and jumping right into the deconstruction.
I don't believe it's been officially announced anywhere, but the evidence points to Fabian Wagner (one of the rotating DPs on "Game of Thrones").Has it been announced who the director of photography is? Having rewatched both MoS (Amir Mokri) and BvS (Larry Fong) recently, I liked the MoS photography more than BvS. But Snyder seems to prefer working with Fong, so that's probably that.
