I confess to being a traditionalist and like cameras in their original livery and not pimped up. In 50 years time people will be searching the net (or whatever has replaced it) arguing about how many purple or pink cameras a manufacturer actually made. I have seen a lime green Exakta, a white Mamiya and a pink Minolta over the past few months -Yuk!
Contaxes and Yashicas usually need re-covering, that rubbish rubbery coating makes them look shabby and unpleasant to hold. I suppose if you got fed up of the lime green, you could put a nice black skin on
