Optical illusions are simply the best. They prove that our minds work in incredible ways. In this optical illusion, you are shown a black and white image of a castle. The image then turns into an inverted color image of the castle where you are asked to stare at a single black dot on the castle. After a few moments of staring the black and white image returns, only you see it is full, brilliant color.
I must say, I was rather blown away at how incredible the color was portrayed. look away from the image briefly and you will see that it is in fact a black and white image!
Have fun & share!
