    Humans recognize far more colors than most creatures on our planet. However, this makes it quite easy to fool them. Here is an example created by Professor David Novick of the University of Texas at El Paso.

    Answer this question: what color are these spheres?


    The answer is: that they are RGB 255,188,144, and in plain English they all are light brown.

    Spiral Colors


    These spirals created by Professor Akiyoshi Kitaoka use only three colors: pink, orange, and green. However, most viewers still see blue, which doesn't actually exist. It too uses the same trick as the above spheres. How is this possible?

    The effect is referred to as the Munker-White illusion (originally only two colors were used to create it: white and black) and it distorts our perception of colors. And it does all this by using small stripes of different colors to separate the other elements. This causes our brain to distinguish colors incorrectly. The effect is more striking the smaller the picture is. That's why it's perfect for the age of mobile phones. When you can enlarge both images with graphics live, you will see the colors mentioned.

    The same correlation occurs in the image below. Only white, pink and green pixels were used to create it. And yet you see another shade right?
