Most people don't want to. Rentals and often even homes for sale take on these colors because they're the most inoffensive. Everybody wants some kind of color and character to their home, but nobody will agree on exactly which kind of color or character. As a result, those responsible for selling/renting these places have them take on a "neutral middle": something absolutely nobody loves, but you can't really hate either. Inoffensive.
And since so many people either a) Rent and aren't allowed to paint or make significant alterations (e.g. nails in the wall), or b) Move too often to feel it's worth the effort, lots of people don't bother to change it from the inoffensive, dull, soul-crushing middle ground.
