The armor set uses the regular colors but for the helmet the secondary is much much darker, like the mark vi.
This makes the set look terrible, is this meant to happen or …?
There are a couple Armor Sets and Helmets that do that. The Noble, Hunter, Mark VI, and a few others I can’t remember off the top of my head. I run red as my secondary color and on those particular armors the red turns into maroon. Not really sure why it does that and I don’t believe there’s an explanation for it.
