Personally, I love the look of brassy cameras. Real photographers have brassy cameras, not minty-looking shelf queens. Some posers here in Tokyo actually use fine sandpaper to rub the paint off the edges and corners of their cameras. My old Leica M4 has been used so much that I managed to rub off the chrome finish on much of the camera. I had it stripped and repainted black last year, but it is already starting to get beautifully brassy again...
