How *different* is NJM III? I too am colour blind but not in the most common
red-green or blue-yellow. I cannot see purple or green. Purple appears as
blue and green as brown. Is this rather uncommon?

What did NJM III mean by never before seeing this colour? There are many times
that I cannot identify a colour, particularly when they are darker shades. A
"novel" colour may appear to me as dark blue/black/red/brown. Meaning that you
could tell me it was either of these and I would have to believe you. Lighter
shades of these same colours do not appear to be a problem. Often I
would have to say I had never seen these colours before. How else could I
explain my inability to distinguish these colours? Unless I have some kind of
very selective colour agnosia. Wouldn't that be a kick? What about NJM III?
If you showed him the same colour illusion again does he remember it as purple-
Anyways I was just curious.
