Why do I see colors when I close my eyes in the dark?
Just because you close your eyes doesn’t mean your eyes and brain shut down immediately. This extraordinary occurrence is called phosphene, and it’s believed to appear because of light inside our eyes. This light is naturally produced, and our retina responds to it, and we see color.
