Actually, that's very retro. I had purple hair around 1982/3 with a little blue, green, yellow, red, and...whatever I was in the mood for at the time. I remember driving the back roads from Colorado to Indiana to visit my 80-something-year-old grandma at the time, and getting more than a few odd stares. Granny was great, though. I called her a few miles out to warn her, and she just said, "Honey, the world could always use more color." I also remember my parents sticking a hat on my head at my brother's graduation from the Air Force Academy, though the officers who talked with me didn't seem upset by it at all, were all quite interested and very friendly.
