Follow on brigade number question:
If I set aside a hero with Training in Righteousness, when the hero returns do I have to select brigade colors that exist or can I pick any brigade colors I want (e.g., Chartreuse and Gunmetal)? If I have to select brigade colors that exist, do I need to select good brigade colors or could I select evil brigades (e.g., Crimson and Orange)?
Training in Righteousness SA: Set a single-color human Hero aside for four turns. On return, Hero gains two additional brigade colors of holder’s choice.
P.S. I understand that if I assign evil (or made up) brigades the hero won't be able to play enhancements.
