Yeah. The colors don't have much in the way of "stats" like I think you're used to in other MMOs. There are "white" Pink, green gears from dungeons. There are Blues for certain pieces you get from vendors based off of items need like Poetics etc. There are also blues that are crafted or drops from Primal raids. And then there are HQ pieces which DO have a significant stat boost compares to certain pieces.

There are some pieces that have the same name from dungeon chests yet, can have different stats. Swapping a DEX stat for a VIT stat or what have you. But you're a lvl 60 PLD so ... not sure how you got that far without already knowing the differences in colors and why they are what they are PLUS stats on gear.
