My mate at work got a Uni degree in CGI and he says that studio models are a diff colour to the way they look in the films because of the way many films are made, something to do with studio lighting and computers......tbh it all went over my head but he sounded like he knew what he's talking about hes a VERY smart man.  ;D

Happy New Years mate.....i'll forgive you for the choccies as you lead me to this fab place.
