Yeah, Brother Jack is correct as TDKR doesn't really have the dominant blue tones of TDK, but more of the snowy grey thing going on and more contrast with brighter whites. It does also borrow from the previous two films too- as you do get some of that blue from The Bat's lights, and you get the warmer tones too with all the stuff in the pit out in the desert. I would say TDKR has the richest visual palette. It's the best looking Blu-ray of the bunch by far, due to the amount of IMAX footage and the fact that it's a proper transfer. However, a new transfer of TDK might make it a tighter race. But I'm just going on the versions of the movies that my eyes are most used to at this point.
Mind you, I love the visuals of BB and TDK too. Both films need/deserve better transfers than what we've got currently.
Also, I really do wish for future releases they would have an option to have TDK/R maintain the same aspect ratio throughout, like they do on the DVDs.
