I usually have black & white of the same model, I can't seem to stick with the same color for a year. The iPhone 5 I had white, black and black. 5s I tried the black while I was waiting for my gold but didn't like. So far I'm liking the gold, even though it looks silver at times.
i went from a white 5 to a white 5s. i wanted the black or the gold, but none of them were in stock so hell i got the white 5s. don't regret it to be honest.
I had the white iPhone 5 and was thinking about getting the white 5S or the gold. But I decided to go with the space grey because I thought that the cases that I wanted looked better on the space grey. But naked, the white and silver looks the best.
