Black & White & Red All Over

I was wondering what fool saw a goldfish and thought it was gold. It's orange. I would the So-and-So was color blind, but that's a stupid term too. Folks who are blind can't see color, so it's kind of redundant. My friend is not color blind, but he has trouble with his greens and browns. Another friend, on the other hand, was truly color blind since he only saw in black and white -- but even then black and white are colors, sort of. Black is all colors and white is absence of color.

I could go on and on, but I'm giving myself a headache.
