This optical illusion causes us to see different colors of the same balls: what happens?

These spheres in the image you will find above (or at the bottom of the news), they may all look different in color but, in reality, the tonality is the same for all of them. It is the optical illusion, caused by the effect called “Munker-White illusion“, which shows us the different colors.

The image – simply called “confetti“- was created by the engineering professor of the University of Texas at El Paso, David Novick. The illusion is created because “our sharpness for form is better than our sharpness for color, which means we perceive shapes with more detail and colors with less detail“declared Novick himself.

The color of the spheres, therefore, it becomes very similar to the color of the stripes that cross them. Scientists have conflicting theories about what is happening in our brains to cause this shift in perception. Some think the illusion occurs during visual processing, when light first hits the retina, while others think the effect occurs later as the brain processes the data (although it could be a combination of both factors).

Novick is currently studying these illusions and in leisure time even delights in creating new ones, but always with the same effect. One of these posts, a 2D version of the confetti illusion, went “unexpectedly viral” on July 18, 2018. Speaking of viral illusions: do you feel the cause of this auditory illusion? While many see a man in this illusion, what about you?
