The image created by Akiyoshi, a professor at Ritsumeikan University and optical illusion researcher, is a hot topic.
In 2024, various visual illusions were hot topics on SNS. In particular, the optical illusion images of Akiyoshi Kitaoka, a professor at Kyoto Ritsumeikan University and optical illusion researcher, attracted a lot of attention.
It looks like a white face and a black face, but in fact, they are the same gray. It is an optical illusion that occurs because, in addition to the difference in color itself, the difference in luminance of the surrounding shades affects our perception.
This illusion has been a huge hit on several platforms including TikTok, and has been tested with Photoshop’s eyedropper tool and paint to verify that it is indeed the same color. Akiyoshi has been repeatedly using this optical illusion and creating new versions.
