Whoa, a group for colorblind artists? I never thought it existed! :'D
I can't really see greens too well, or oranges either. But I also have troubles with blues and violets. Have not had a true exam; been waiting for years to schedule one. Learned about it when I was about 13, and that gave me a shock, since I'm a girl. The nurse at school was pretty shocked too.
So
YEAH!
I'm gonna try joining! :'D
