OT, but I can't help it. A friend of mine is in art school, and one day for fun, he had me look at his color wheel with literally thousands of colors. He asked me to pick my favorite color without looking at the names. The names were actually these bizarre codes of color, shade, and something else. Idk, WAY over my head. Anyway, by the time I was done, I handed him the card I liked best. He flipped it over, and it's technical name was... wait for it... blue. Just plain pure blue. So out of thousands of colors, I picked an absolute pure color!
So... maybe us men really do see colors, but it's a mental block. Just a theory
