Since the release of Azteca, a friend and I have found that our armor seems to dye itself. We are both wearing the Prestigious Style, from the Massive Fantasy Palace Bundle, for our robe and boots and they are stitched with other stats. Prior to the release, both of us had dyed fully white but logged on to a white base and light green trim for both the robe and boots. Our hats are not from the Prestigious Set and are not affected so it seems to be an issue with the style. After paying about 10,000 gold to dye back to full white the other day, I logged in today and found my gear to now be dyed with a white base and orange trim.
