PvP gear color glitch
It is not a glitch, they made it so you could customize what your armour looks like in the PvP matches so it will match the color you have in the mists, all enemy colors will be the proper color of their team however. If you don’t like this system they have stated before that they will be implementing an option to change it in the upcoming patch.
It was a update they didnt mean to implement yet and is being worked on
