Old Japanese, and other Asian countries apparently, had the same word for blue and green. So this is what portrays of her hair which are greener refer to. I would not be able to explain why, but colour theory involving the primaries blue, yellow and red are fairly modern concepts.

Yes... People knew even then and world wide if you mix red and blue you got a purple colour... But... They had some ideas missing and didn't understand why. Its simple logic to us, just as simple as the concept of "0", except even we struggle with this concept sometimes.
