actually, color pallet is more often than not manipulated to set mood. All those wartorn shooter environments are pushed to certain color pallets because it gives a dismall feel, not necessarily because a village full of wreckage actually looks like that. Take games like Resistance, for example, the real world doesn't look like
this . And it isn't just a problem with Resistance,
Gears of War ,
GRAW , and even
Call of Duty all do the same thing manipulating the color pallet in favor of mood and less for realism. Mario may be more cartoony, but the more vibrant colorpallet actually mirrors real life a little more closely than the more "realistic" games which mute everything or turn it to brown.
