When is blue not really blue?

Anyway, my point is, it's a lot more complicated that just saying "you're albino"

Thank you for agreeing...

Now we´re back to the labeling dilemma!

There could be a bunch of different causes for similar visual effects,
but the common labeling system for colour morphs is trapping
to multiple mistakes.

I suppose so. That's why I just keep calling them like they appear. They are blue, they lack red. "Blue anerythristic"
