Simple Optical Illusion Fools the Internet

In a short video posted on June 6th, 2025, Spanish technology expert Toni Reboredo (@fast_byte_informatica) presented a simple yet compelling optical illusion. The video, which has already garnered significant views, shows two stones that appear to be different shades of gray. However, Reboredo explains that they are, in fact, the same color. The illusion works because of the way our brains interpret light and shadow. "It's one of those times when you see photos like this and exaggerate what you see," Reboredo says in the video. "The optical illusion is incredible! They are the same color!" The video encourages viewers to test the illusion for themselves by covering the dividing line between the stones. This simple experiment highlights how easily our perception can be manipulated, reminding us to question what we see. The video's popularity reflects a broader interest in visual perception and the power of optical illusions.
