Between Blue and Purple

This is strange to me. I call these flowers purple, so why are they called 'blue irises'?
This is a small point of historical contention because in seventh grade I argued the point with a girl that I know didn't like me much anyway. She was haughty and probably considered herself better than me for no real particular reason.
I must have said something about the purple coat she was pulling out of her locker and she shook her head, "No, this is blue." I stood my ground on the blue platform, but a small place in my nervous adolescent heart wondered if she had reason to feel superior to me: did I not know blue from purple?

Yeah right. ("That was the last ice cream sandwich? Seriously? I had no idea.")
