drained colour in games

I am finding WoW very desaturated on my new macbook pro. With windows I could tweak the contrast and such in the nvidia preferences. Is there any such option here?

try adjusting the gamma setting in game.

If you look at the Mac options there is a section describing gamma correction. If you are playing full-screen, I believe the gamma correction setting in game are what you are after. If however you are playing in windowed mode, the system gamma correction settings are what you need to adjust.

Not sure if this will help resolve your problem, but it's the only thing I could think of.
