Friday Fun: check out this rainbow ghost optical illusion

ghostly rainbow optical illusion

John Shadowsky introduced a new kind of optical illusion he invented. I’m talking about one that gave us ability to see black and white photos in full color! This is the closest you get to having super-hero powers. It was really an extraordinary value added to the optical illusions field, but also an interesting phenomena brought to attention of those studying visual sciences. The below rainbow is just one of many emerging samples, based on John’s discovery.

To see this optical illusion in it’s full capacity, wait for the animated .gif to loop to its start. You’ll know you’re there when you see a full colored rainbow appear. Now stare at the center dot for few seconds, and at one time the animation will switch. But don’t move your eyes from central dot just yet! What do you see? If you followed my procedure precisely, sooner or later you’ll find out that the animation below consists of two similar images. Only difference between them, is that one is in color, and the other is black and white. After staring at the color rainbow’s central dot, negative colors burnt in your retina, and you were able to see the black and white photo in full color!
