True, you can't exactly call the bridge scene "Vibrant," and i agree, most of the vibrant colors are in spider-man's suit. It's pretty easy to get color in the characters when one is a giant green monster and the other is wearing red and blue spandex though lol. That's just how a Spider-man movie is going to be, a little colorful.
Also, for the school fight, for me at least, maybe my eyes were messed up during one of my viewings of either movies, but daytime in TASM looked a whole lot different than daytime in TDKR.
EDIT: probably because it was all snowy in TDKR
