The name colours of these items are not yet confirmed. White items seem to be normal, but purple are unknown. There were no purple named item types in Diablo II, so it's unknown if these are analogous to Rare, Set, or Unique, or are an entirely new type of item. Also keep in mind that item stats are the sort of feature that is highly subject to change during development.develop Diablo 3 is showing alot if similarity towards the blizzard game world of warcraft, so im just taking a guess the purple items are either just another magic item or like in WoW might be an epic item,as for the pots they are just like in WoW some give buffs and some might not not sure yet
