Go here, do what it says. It is not one of those stupid things that leaps out at you and scares you half to death, it's just hella cool. :-)

I guess that some color information remains on the back of your eye, (similar to if you watch TV in a dark room, and turn it off - you'll be able to still see the frozen frame even though nobody else that just came in can see it). Then the image overlaps with what you see and hence the color...
way cool! |

That's amazing. Astonishing how long the color image stays imprinted, as long as you don't move your eyes...

That's one of the best 'after effects' I've seen. Thanks for sharing!

I truly must be different from the rest of you folks. I started out with an image replete with colours and stared at the dot for the prescribed amount of time.
Then, as I move the mouse to the image I see what......a black and white image.
I have tried this 4 times now.....same results. Maybe I need to lie down for a bit.

| Have you ever noticed that if you're in a bright light with your eyes closed a while, hence seeing red thru your lids, that when you open your eyes everything is colour shifted? It's the same effect. Your brain knows what colour most things should be, so tries to adjust them to the "right" colour. When the colours are returned to normal, it has to readjust, so an afterimage is left until it does. It's fun to play with, though! :) |

If you will notice that is a negative image. I studied that in a psychology class. The visual that is retained by your photo receptors is a negative of the actual color info recieved.
The grey scale image just brings back detail for you.
