Default I see colors

when I close my eyes. Always have. It'* kinda like a retained image thing, but it quickly fades to a blur of yellows, reds, greens, and blues. The blur moves around on it'* own for the most part. If I close my eyes really hard, the colors will brighten momentarilly. It happens in a dark room, too, and looking at a dark spot in a bright room. Like I said, it'* not a new thing. I think it affects my night vision some though, seeing color that really isn't there to see. It tends to fade after my eyes acclimate to the dark, but never fully goes away.

Is there a name for this? I tried describing it to my wife and she says it doesn't happen to her.

I have almost the exact same thing you're describing. Do you sometimes see outlines of your retina when you close them, too? I never really thought it was unique, but it is pretty cool now that I think about it. Weird...

I think this happens commonly, it'* the effect of the sensors in your eyes still reacting to light you've already seen. The same reason that you see spots after a camera or the optical illusion of looking at a red/blue picture of the house on the hill, then looking at the black and white picture, which turns into color because of the residual color you're still seeing. I'll look it up and see if I can find a better explanation...

Edit: I haven't found any really useful info, but it should also help if I mentioned that your rods and cones have sensitivity changes, as in once they fire off, they need to "recharge" and that they adjust to light and dark stimulus. I'm not sure if I'm right, I just learned a bit about eyes in my Psychology course.

So basically what I'm guessing is that you're getting a residual amount of sensory input from what you've already seen. A good way to test this would be to close your eyes and see if the patterns of colors correspond to the light stimulus around you. IE, if you've been looking at a computer monitor, there would be a rectangle in the center of your field of vision, probably blue or purple. Also, if you're in bed in the dark, and you close your eyes, the amount of color you see would be minimal. Just my $.02.
