My room is an ugly off-yellow/off-white combo. I hated it when we bought our house, but trust me, the walls are a whole lot more ugly when they're naked. I suppose I have more random junk than the normal human, but I've got posters / plaques / bookshelves / paintings covering at least 30% of my wall, then my desk and dresser (and the things on top of them) cover some more. Take my philosophy: if it looks bad, cover it.
