A Professor at the University of Texas at El Paso David Novick has posted on his Twitter page an unusual illusion. At first glance, it can be seen in the circles of four different colors, but in all actuality they are a pale apricot and from each other do not differ.
This effect is called “the illusion of Mancera-white”. The observer it seems that the circles are different from each other, due to the fact that each of them is “obstructed” by the stripes of different colors, and it confuses people confused when it tries to evaluate the color of geometric shapes. The scientist that demonstrated the illusion, he prefers to define it as “confetti”.
Here’s a second confetti illusion. All the dots in the background are the same color (RGB 248, 205, 172) but are perceived as four different colors. Like all Munker illusions, this is affected by image size. If the illusion isn’t clearly apparent, try shrinking the image. pic.twitter.com/VXjtbIovhm

The Professor notes that the illusion only works if the image is not too “stretched”. In this regard, he recommends that those who clearly see the circles of the same color, to try to reduce the size of the image. Those who can’t believe that the circles do the same, should, on the contrary, to open a picture on the entire screen of the computer.
Internet users found the optical illusion is quite spectacular, and some were able to create a similar image using the same technique.
There are many illusions, demonstrating that man cannot fully trust your own eyes, appreciating the color of the surrounding objects. As a rather visual demonstration of this can result in a photograph last year showed Japanese psychology Professor akioshi Kitaoka from Ritsumeikan University. Strawberry in the photo almost everyone will seem red, but in reality the picture is not any of the red pixel and the color of the strawberry is perceived as such due to the fact that the human brain makes a “correction” on a blue background.
