Well, I don't know why we see the red. I do know that when I take a washer with about a 3/8th inch hole and slide it over the picture on the screen the red disappears. The outside of the washer is big enough to block the image so the there is no suggestion of a coke can. Same image, same backlighting, different look. Make a hole in a piece of thick paper and try it yourself.
