If you let me cut a hole in your skull and attach some electrodes to your brain, I might be able to tell you, after a few years of research.
I suspect that at most all you would be able to do would be to show that the electrical signals caused in my brain when I look at the color green are similar to those in the brains of most people with normal color vision when they look at the same color, not whether what I think I see in my "mind's eye" is the same as what they see.

I never dreamed that I would see the last.
