Recently, Amber has shifted to my favourite colour spot, but none of the red dyes are yellowy enough, and none of the yellow dyes are red enough. I think amber is a really cool and understated colour that would be of great benefit to many potential future glams. There's a lot of variance behind the more yellow-ish amber, the more orangey sunset amber and the deep red kind of amber that I'd love to see in game.
Plus it's a colour that would most definitely fit Dawntrail's and also what better way to further hype two dye channels than with some all new colours?
