Those orange ones actually look pretty sharp: not my kind of thing, though. I really prefer black: it doesn't do for me to have too eye-catching a color when I'm working.
I suppose if I were in the market I might consider the chocolate or olive or tan, or in mix and match just the black with brown grips. (Yeah, I like earth tones.
A dark matte grey like the old P30t, (since I seem to be the only one I know of that actually likes that color,
) or those grey Voigtlander R3s might be neat, particularly with brown grips. I've considered doing up my Canonet in that scheme.
Someone had a silver one with brown, very classy.
I think in the final analysis I'm more interested in thinking about camera color schemes than in using anything much flashier than black.
Still, if you got a white one you could like walk around going 'Spensaaaaaa.'
