Any genderqueer person comfortable enough in their identity to wear it in public can tell you that their flag colors demonstrate that green and purple go together quite well, thanks.

I once was attending an SF convention with a top and a reasonably complete set of jewelry in those colors. Got a big gender win when a panelist at a gender panel I was attending asked whether the colors of my outfit were significant, and I could respond affirmatively and thank them for noticing. Which led to a very nice extended conversation.
