America in Color from 1939-1943

As I said, "perception of color can vary." But it is entirely possible to determine that something is green without rods and cones being involved.

But that is not the same thing as the world is black and white and color is simply a creation of perception. Any more than light is a creation of perception since the ability to see it can vary from person to person.

Indeed. If what iSm said were true, then those paint color matching machines at the hardware stores wouldn't work.

In case anyone cares, the devices are called a spectrophotometer (they are used quite a bit in the printing industry).

If you want, I can bore you silly with discussions on color theory, additive vs. subtractive color, etc. Hey: I took an entire course on this, I have to impress somebody with my knowledge.
