Unless you're going to let the phone be naked, does it really matter much what color you get? People always slap a case on it and you never see the phone's color anyway.
Personally, I keep my phone completely naked (no screen protector or case) because I don't like the added bulk of a case or the look/feel of a screen protector and my phones have always been just fine. Very small signs of wear, but big deal. I prefer the black front bezel to white, and since there's only 1 option, space grey it was for me. But I also happen to like the space grey color as well, so win/win.
