The most famous case on this is JELLYBEANS, a revocation case filed to revoke that mark for candy products.
The test at the TMO is low and so many such marks are registered. It is essential to search well to avoid running into conflicts with registered descriptive marks. Even using descriptive tag lines is risky without searching. Of course you can sue to revoke these marks, but this is an expensive defensive option after you have run into trouble. Safer to know the position in advance.
