Square Changing Colors Optical Illusion Akiyoshi Kitaoka
Japanese psychologist Akiyoshi Kitaoka has created what might be the next viral optical illusions and it involves a simple square. Why makes it so special? It appears to travel across a rectangle that’s dark salmon and blue with it blending together in between. However, the quadrilateral appears gray while moving in the pink space and then turns pinkish when in the blue.

Why does this happen if the pigment is the same? Scientifically speaking, it’s caused by a principle known as the chromatic induction effect, where a perceived color shift that occurs when one colored object moves around an identical stationary object. In other words, the perceived saturation of the stationary object decreases whereas the saturation of the moving object increases. Just like this infinity cube lamp, it’s all just an illusion.
