Like "Rotating Snakes," this illusion was also created by Japanese psychologist and professor Akiyoshi Kitaoka, who studies visual perception at Ritsumeikan University. Professor Kitaoka shared the photo on Twitter earlier this year.

The color red has been completely removed from the image, yet people still see red strawberries. Why?

Well, as INSIDER's Jacob Shamsian explained, the brain "knows that the color of an object is more useful than the color of a light source" in determining the color of an object. Thus, "it's trained to ignore information" it receives about the color of a light source. Since your mind recognizes that the objects in this photo are strawberries, and it knows that strawberries tend to be red, it color-corrects the gray and green pixels in the image to be red.
