Optical illusion sparks heated debate over color perception

Optical illusions can really mix things up online. Such images are often created to be interpreted in various ways, allowing everyone to see something different. It’s the same with this particular illusion. It appears to be a remarkably simple image where, on a colorful background, we see two square blocks placed at different angles.

Although the illustration seems uncomplicated, it has attracted enormous attention. That's because, according to people sharing this image on social media, both blocks are the same color. Many people strongly disagree, claiming that the bottom block is white and the top one is gray. What do you think—are the blocks identical, or do they differ in color?

If you cover the middle part of the image, you'll see that both blocks are indeed the same color. The confusion arises from the effect of light and shadow and our ways of perceiving them. "Same color, different light, learn, buddy," noted one commenter. "That's how light works," added someone else.

Even though a clarification regarding the interpretation of the image has appeared on social media, many people remain convinced that the bottom block looks lighter. Even graphics explaining this phenomenon do not convince the skeptics.

Optical illusions typically work through misinterpretation of light, shadow, or colors. They mislead viewers, giving the impression of seeing something that doesn't exist in the image. This resulting illusion is a consequence of disruptions in perception mechanisms that normally assist us in perceiving. Interestingly, most people don't consider the fallibility of their brains, often leading to heated discussions online.
