Well, here's yet another 2-cents: photographs are display most often in a white matte. The surrounding environment affects how you perceive color, any number of tests prove that, and it's not something you can "get used to" either, since it's built into our brains. Therefore, working in a light background and environment is really quite important for accurate work, color or B&W.
Take a look at these if you think you can see without being so influenced:

I've seen this in myself and in others, so I too am voting for a color ui that looks more like the background here, rather than the currently fashionable but ultimately harmful dark one.
