Colour Changing is a survey going on currently in Announcements, I personally Don't want colour changing because I think having a natural Yeep colour makes us Unique.
My Idea is that we can't change our colour but we can change our Fabric Pattern like the concept art, This allows us to stay unique while adding more customizability options for people who want to decorate themselves with patterns rather than ordinary Cosmetics.
Patterns could also appear on your hands because, as of now, hands can't really be customized without using gadgets that go on your wrist.
