> Suppose that I see red the way you see green. Then, when I see a stop sign or a fire extinguisher, I'm seeing the color that you would call "green". Are you sure it is possible to pluck the color I'm seeing out of my head, and the color you're seeing out of your head, and compare them side-by-side, like we could compare two different colors of paint on a piece of paper? I'm not so sure about that. It seems to depend a lot on what phenomenon "how you see a color" actually refers to. If "how you see a color" refers to the neural patterns excited by light of the relevant wavelengths, and you and I have the same neural patterns, then we see the color the same way. There is no metaphysical layer on top that can make one of those experiences green and the other red.
