What Iphone is worth more a White iPhone 3g or a black one?

Title says it all, both are in the same condition which is worth more the white iPhone 3gs or the black one. Not the iPhone 4 but the 2nd one that came out.

Hopefully the black and white iPhone 3GS would be the same price, unless the seller wants to risk racial discrimination. The two phones, since they are exactly the same, will be the same price if you are purchasing them from a valid seller, like AT&T, Verizon, etc.
