Now, a new illusion has been created, which tricks your brain into thinking that identical dots are different colors.

The illusion features two gray dots on a background consisting of a gradient from light gray to black.

Although the two points are really identical, they look very different based on where they are placed in the background.

Now, scientists at the Massachusetts Institute of Technology (MIT) have revealed the science behind the illusion and say the phenomenon depends on estimating brightness before visual information reaches your brain.

Professor Pawan Sinha, who worked on the study, said: “All of our experiments point to the conclusion that this is a low-level phenomenon.

"The results help answer the question of what is the mechanism behind this fundamental process of estimating brightness, which is the foundation of many other types of visual analysis."

In the study, the researchers studied nine blind children in India who underwent surgery to save their eyesight.

The children were given the illusion and even saw the spots in different colors, indicating that the brightness estimates are based on a simple brain circuit, rather than on previous visual experiences.

Professor Sinha said: “If brightness estimation is really a low-level process and the circuit is located as early as the retina, then perhaps it is an innate dispensation.

"This is something that the visual system has been prepared to do, since birth."
