An optical illusion in which viewers guess which marked square on the chessboard appears lighter than the other is going viral.
The viral illusion sees two squares on the chessboard marked A and B.
Viewers had to guess which square looked lighter or had the same color as the other.
Edward H Adelson created the optical illusion in 1995.
The Perceptual Sciences Group in the Department of Brain and Cognitive Sciences at the Massachusetts Institute of Technology shared it on their website.

It turns out that the color of squares A and B are the same. The reason is that two gray stripes overlap the marked ones.
Previously, an optical illusion in which the viewer had to search for a cat among a large group of women made the rounds. As they are known as the ‘mental gym’ for human brains, the well-trained cunning will be able to find the animal within 20 seconds.
Not yet? Do I need a hint? He is a gray cat next to a lady with a scarf.
