Only it's the story of the teacher who stood there at the end of the day and said in a very scathing voice, "Someone thinks they have green hair." I was... maybe five or six? Not a happy memory, that one. (Fortunately she was only a supply teacher - a temporary stand-in)

And that might answer your question, actually. The problem is that I can't really see green - it just blurs into the colours on either side. Only of course you learn colour names to some extent by rote, so it's not that simple.

My favourite example is the MSPaint colour pallet. The yellow/lime green pair look identical to me, as do the pair underneath them; I'd say they're all yellow. The vertical pair immediately to their right are also identical, and both green - I guess one is actually a dark yellow?

And just in case you thought you understood - everything to the right of that is blue. The colour I have no headspace for at all is purple; my colour wheel goes from red to blue, possibly with a very limited pink in between.

(Which implies that the problem should be with my red-perception - but red is so vivid, and green is so boring and, when dark, just brown... yeah, I dunno)

Tell you what, here you go: a colour wheel.
