DC's films tend to be a bit darker than their competition, and Zack Snyder's Man of Steel film is no exception. Superman wasn't a bright figure in a vibrant world, striving to do good, he was a gray figure in a mostly drab existence. This video, featuring some rough color-correction, shows what the film would have looked like if color had been allowed to shine through the drab presentation.
"The results we achieved are obviously a bit oversaturated and contain contrast artifacts. Since our source footage already contained severe color-grading decisions, it was far from optimal and, at best, this is an approximation," the video's text reads. "If the raw footage had been colored in a more natural and pleasing manner, it would actually look SIGNIFICANTLY better than what you see here."
Here's a neat detail; the film may have originally been much brighter. "The orange-tinted sky in the Metropolis aftermath shots and the purple girders behind Zod were actually there naturally. We believe Man of Steel had a more traditional-looking color grade until later in post-production when they decided to go darker. They should have followed their first instinct," VideoLab wrote.
So what do you think? You can watch the Batman v Superman trailer below to see the color palette of that films as well, or at least an idea of what it might be.
