Why do DM's tend like Dark, gritty worlds and players like colorful worlds where they can do/play anything?
Actually, I don't think those two are mutually exclusive.
As a DM, I know I generally prefer 'dark' campaign settings because they're easier to set adventures in. There's always something going on wherever you go, so there's always something for PCs to do.
By contrast, a 'light' setting has the problem that it is probably dominated by a single central conflict, which is fine... unless that players aren't really interested. Then, you either have to deal with bored players, or you have to deal with railroading them into the quest.
As for players liking worlds where they can "play anything", I think that's only natural: people like having options. I do think the vast majority of players will accept not being able to play anything, just as long as there are enough options.
(Of course, there's sometimes that one guy who just has to play an option you aren't allowing, just to be difficult/different. But that's a 'problem player' issue as much as anything. Just as there is that breed of DM who closes off lots of options without reference to his players' preferences, and often 'just because', which is likely a 'problem DM' issue.)
But it's certainly possible to do a dark and gritty setting and still have a wide range of races and classes available.
