I always thought that I was a bit colour blind, maybe not.--

The room is darkened, and Mr. Land (founder of Kodak, if you're having trouble placing the name) talked while everybody's eyes got dark-adapted. He had a collage made of bits of colored construction paper, which included a big red spot that was round.
When he figured it had been long enough, he got the projectionist to shine a beam of white light, very faint, on only the red spot. Having no context, we saw it as white.
He then had the spot widened. Same illumination exactly on the red spot, only now we could see swatches of other colors. Instantly, we saw the spot was red.

This was helpful and interesting, though.--
Ike's jacket is OD Green and his trousers are a khaki tan. Do they appear identical in color to you?

I have a pair of pants that are navy blue in sunlight and incandescent light, but a dark green (with no hint of blue) under most fluorescent lights.

I didn't exactly say that the entire second row was green to me. I said that with a liberal interpretation of the word "green," arguably all those tiles fall into that category to some extent. Color is a linguistic as well as a perceptual concept. (Given a set of colored cards to sort into piles according to which color they are, people with different mother tongues will pretty consistently sort them into different piles.) That photo of your hat appears brown, but I can see that it might look green under some conditions.
Here's my graph (I closed the window the first time round, so had to redo it; the results are remarkably consistent however):
Last weekend I discovered this incredibly print-geeky iPhone game: Eye vs. Eye. (Well, to be truly print-geeky you'd have to compose colors in CMYK, but that's not really possible on a screen.) It's interesting in that it tests your color memory as well as the completely unnatural skill of being able to discern the R, G, and B ratios that make up a color. Mildly addicting, especially since I've always been in awe of production experts when I've watched them color-correcting proofs. (Kern and Press Check were too geeky even for me, however.)
