I have the Turkish green (I think of it as Tiffany blue, as in those shopping bags). I wasn't sure about the color either, but it grew on me. I wouldn't have chosen the color, but I got the bike (barely) used from a friend for less than half retail, so I can't complain. I get that the wrong color can nag at you, but I told myself that the function of the bike is more important than the look, and now I'm quite attached to that bike. I didn't find the color too feminine, and I'm secure in my masculinity.
More important than the color, this bike is a three speed, and I would have opted for a six speed. Three speeds are fine for my city riding, but limiting if I go further afield into hillier territory. I thought about upgrading the Brompton, which also would have given me the chance to pick a different color. In the end I opted for for a second bike, a 20 speed Tern, which gave me a wider gear range and a somewhat sportier ride. So maybe this is an opportunity for an n+1?
