Zack Snyder's color palette was one of the biggest complaints that many fans had going into Man of Steel, and coming out of it, the general sense of bleakness many felt the movie suffered from was certainly tied to that palette in many of the critiques of the film.

Lighter blue, anyway. And with more yellow in the shield.

That's not a bad look on him...!
