The original vex armour was a dark muted blue, and copper. When you preview the ornaments in the armour piece screens, the ornament shows up in the same colour scheme, which is the one I would expect, but once you come out and see it on the character in game, it has become this blue colour not too disimilar from the timeglass shader (no, I do not have a shader equipped). Furthermore, the vault of glass cloak has changed its in game default of white and gold, to green and gold. Not sure if intentional. Only happens on the 390 version though. Original still white. Clarification that I'm only talking about hunter armour
