What is blue text on equip description?

The white text is the base stats for the named item (Brigandine, Plate armour, etc) which will always appear, increasing with level of the item. The blue text is the unique stats added JUST on that particular item, randomised from I can tell but boots will most likely have movement speed boost, DEF boost or some sort of resistance. Whereas rings and bracelet (or necklace?) will often have blue text of increased chance of item drop, which is indispensable to farm for loot with better unique stats (blue text) Once you equip the item, previous equipment will be broken into nothing. You can ways preview the stats of the current gear and new ones by tapping on the new item in your inventory.

But the items will also have a rarity, shown by their backgrounds (grey, blue, gold). The shades are somewhat pastel and can be hard to distinguish to some.
