Common items are items that can be bought from NPC characters. All common items have a blue name. Some rare items, such as the Stick of Roritoren, are rare but have a blue name. There are several rare shields, and they all have blue names. There are many weapons for each class, with the exception of Acrobats, that only drop from monsters and give some stat bonuses. They used to have brown names, and although they are hard to find, do not sell for much. Cash Shop items have blue names, but whether or not they fall into the "common" class is debatable.
