Optical illusions can shake things up online. These images are often designed 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 we see two square blocks placed at different angles on a colourful background.
The same colours or two different ones?
Although the illustration seems straightforward, it has attracted enormous attention. That's because, according to people sharing this image on social media, both blocks are the same colour. Many people strongly disagree, claiming that the bottom block is white and the top is grey. And you, what do you think—are the blocks identical, or do they differ in colour?
How was such an effect achieved?
If you cover the middle part of the image, you'll see that both blocks are indeed the same colour. The confusion arises from the effect of light and shadow and our perception of them. "Same colour, 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 are still convinced that the bottom block looks lighter. Even graphics explaining this phenomenon do not convince the sceptics.
Optical illusions have always stirred emotions
Optical illusions typically work through the misinterpretation of light, shadow, or colours. They mislead viewers, giving the impression of seeing something that doesn’t actually exist in the image. This resulting illusion is a consequence of disruptions in perception mechanisms that normally help us in perceiving. Interestingly, most people don’t consider the fallibility of their brains, often leading to heated discussions online.
