If I close my eyes, I can imagine a color. Furthermore, I can even see it in some circumstances, such as under the influence of certain drugs or in dreams or just before falling asleep. But how is something like this possible? How does the brain "invent" the effect of electromagnetic waves to represent colors? How does the "screen" that we have in our minds work?
