What color kitchen appliances should I get?

I am buying a new house and have the option of choosing either a white, tan, or black oven/stove and dishwasher. (I'll have to buy the refrigerator myself.) Which looks nicer? Are there any pros or cons of any of these colors? I will have darker cabinets (not super dark, but a dark wood color), and will most likely be choosing a darker granite color for the counters. Thanks for your input!
