Take a look at this image of two blocks on top of each other. How do you see the gray cubes in this image? Same color or different shades? Know that the two squares may appear to be two shades of gray, but they are actually the same. You may be wondering how this is possible, but here we will explain!
To be able to change your perspective to different tones, do the following: place your finger positioned in the middle of the two squares, on the white part of the block. Do you notice something? Now the two blocks that looked different are the same color.
The optical illusion described in this text is known as the Cornsweet illusion, after it is named after psychologist Tom Cornsweet, who created it in the 1960s. Thus, it is based on contrasts, so when this illusion contrasts, the blocks look different.
Cornsweet is known for his work on visual perception, noting that humans perceive colors and tones in 3D images depending on how objects are in the light and how shadows fall on they.
If the light comes out of the upper left corner, the two squares appear to be at an angle tilted away from us. In this illusion, as the light source comes from this top left corner, we notice that the top block is in light, while the bottom block is in shadow.
That way, if you combine the shading that's contrasting between the two gray blocks, our brain interprets the top block as darker and the bottom one as a lighter shade.
