Lex wore red and Sebastian wore yellow. There was more yellow and orange from the scenes set in Mexico, the establishing shot of the tracking station, and the Weyland logo, which is everywhere, was yellow, too. There was plenty of blue throughout the film, either in the locations -- dark blue -- or set dressing.
But seriously, what the hell. Most of the friggin' movie takes place in Antarctica, a country not exactly renowned for its broad colour pallet.
You're honestly trying to tell people you think AvPR looks better than, say, Sin City? Or Casablanca? Or any of a hundred beautiful movies shot in black and white? Get off the grass, man.
