The third and final trailer for Justice League featured a new, red color palette that sparked several questions amongst audiences.
The latest Justice League trailer prominently featured red skies, something that’s drastically different than the blue skies shown in the movie’s previous trailer.
While that may not be what’s happening with the movie, we can’t be sure until Justice League hits theaters next month.
That seems like the most likely reason for the red skies in the trailer (and the movie).
