Given what he went through in Batman v Superman, if it's the update to the Superman costume we think it is, it'd make sense. If it isn't, then we're being fooled by an Instagram filter and in that case damn you, Henry Cavill, you sneaky devil.
The internet is abuzz thanks to Henry Cavill taking to Instagram to tease his Justice League filming courtesy of a new picture of the Superman suit:
Naturally, comic fans are flipping out because they believe Cavill is revealing that Superman will don a black suit in the movie — an homage to his uniform in The Death and Return of Superman, the arc from which Batman v Superman borrowed, which features Doomsday and Clark's battle to the death.
In the comics, when Clark came back following his death at the hands of Doomsday, he sported a black-and-silver costume with no cape. But the costume Cavill snapped looks like it would be all black... if that is the costume's actual colour. Given the complete desaturation, it's equally likely this is just a black-and-white filter over a picture of the normal costume, and Cavill is just playing with everyone.
But it's not like the black-and-silver costume wouldn't make sense, given it's already from a story the DCEU has borrowed extensively from. If it is a new costume, Cavill better get the glorious mullet Superman had in Death and Return of Superman too:
Those glorious locks.
No ifs, no buts. If it's an Instagram filter, fine. If it's the actual costume? Mullet or bust.
