Stick with darker colors! I made the mistake buying a white PS3 with white controllers. White plastic turns yellow over time due to some chemical reaction.
I know this is silver-ish, but lighter color plastic is generally a bad idea. If you can get darker color, don't get lighter color. The darker, the better.
