Lootamatic

with lootomatic i do not believe there is a way to just select a certain color type of loot for dropping or keeping, but with an offshoot addon called Lootit there is I have been using Lootit for quite a while now and you can select color types, or set it to only keep loot that is a certain gold amount or higher, it is quite versatile. You have to be a bit careful though when setting things cause it can toss out things you want to keep if they happen to have a gold value or if they are say a Green item and you are looting only Blue or higher, you can still put items into a loot list for keeping or dropping same as lootomatic. It is definitely a more versatile addon. hope this helps
