Because it connotes seriousness?
Plenty of serious movies over the decades have been made with a reasonable degree of color saturation. And really, if they don't want movies to be colorful, why not go all the way and revive the lost art of black-and-white cinematography, instead of this drab in-between approach?
Because they want to differ from Tim Burton's visual look as much as possible?
No, because it's not just this film, it's industrywide. Digital color correction has done terrible things to movie cinematography, because so many filmmakers these days seem compelled to adjust their films to have one of a narrow range of different looks, like muted colors or everything tending toward orange and blue. And then there are all the films and shows that try to duplicate the sickly green tint used in
The Matrix, even though it doesn't make any sense to do so -- the green tinge there was meant as a subtle cue that the scenes set inside the Matrix were unreal, not just a random and pointless stylistic touch like the way all the imitators use it.
That may be part of an R. If I could find it. No way is that red. Now where's the R?
Upper left chest (our right), above the "Ke" in "JoKe's on you." Partly covered by the second A and third H in "HAHAHA."
I'm no expert on Robinalia, though my best friend is. He called it as a Nightwing costume.
I don't know why. There's nothing about it that matches any of
Nightwing's various looks.
Apart from the 'R', there's also the fact that ithe shirt is closed at the front.
That's traditionally the way Robin's shirt looked.
Not to mention that those were supposed to be cloth laces, not metal clips or whatever. And it was more of a jerkin than a shirt, since Robin's look and nickname were inspired by Robin Hood. (I was surprised when the Superman radio show's narrator once described it as a red leather vest. It had never occurred to me that it might be leather, but that makes sense.)
