Why Do We See Colors When We Close Our Eyes?

Imagine your eyes are like a camera. When you're awake, the camera is taking pictures, but when you close your eyes, it's still working in the background. Sometimes, your brain gets confused and shows you colors that aren't really there, like seeing swirls or bright flashes. It's like watching a movie inside your head without any lights on.
