Yep, PJ is certainly "coloring" his films. He's even pre-coloring make-up for processing compensation in The Hobbit movies (note the make-up applier's own skin for comparison):
The Red-brand digital cameras now are legitimately a part of it. "Red camera tends to eat color a little so we add more color", said a TH:AUJ production designer in an official blog video about 3D filming. But, if the picture is red-reduced for a general shift towards teal (requiring red make-up pre-emphasis for better flesh-tones after red reduction), then that indicates a deliberate teal-tint agenda going on here.
Good thing we're around to fix it!
