Everything I equip is purple?Follow

If it's purple, it means that the item is too high for your level. This can happen accidentally (easily as it happens *ahem*), by inserting an augmentation that is higher level than you can use (or say a purity aug, which are *ahem* trickier to remove. Good thing loyalty points are free ish). Check the item and its augs and look at required levels. You'll probably find that's the problem.

That could be it. Honestly, I think when I dorked my BP with a purity aug that one time *cough*, it maybe turned yellow? Honestly can't remember the color. Just that it no longer worked. Wouldn't surprise me if there are different colors for different things. I think red is an item that itself can't be equipped, for example. Again though, really haven't stopped to pay that much attention.

The slot is purple or the actual item is purple? If your character is new, that might explain it. All Crude Defiant armor and most of the Gloomingdeep tutorial reward armor (as opposed to the Stitched Burlap eq) is shaded purple. Each tier of Defiant and Consigned armor (Simple, Rough, Ornate, etc.) has a different shade. Purple might be the most glaring, although yellow is up there, unless you're in the League of Canary Paladins.
