Optical illusion of strawberries stumps the internet when creator reveals they AREN'T red

At first glance, the strawberries in this photo appear red. Right?

Wrong.

But as experimental psychologist and image creator Akiyoshi Kitaoka explained, there are no red pixels in the photo.

Yet, somehow, the strawberries look red to us anyway.

The brain teaser that has left Twitter befuddled was uploaded Monday has since inspired thousands to weigh in and led to many disagreements.

See Twitter reactions to the photo:

Kitaoka explained the confusing illusion: "Illusion of strawberry by the two-color method. Although this image are [sic] all made of the pixels of the cyan (blue-green), strawberries appear red."

Similar to the blue dress that divided the internet when users argued over its actual color - the strawberry illusion is created by a phenomenon known as color constancy -- the ability to perceive colors of objects, invariant to the color of the light source.

The attention has caused Kitaoka's Twitter following to explode this week, prompting him to share the original image of the strawberries before he manipulated it.

He also took the opportunity to share some of his other favorite illusions, including these "moray eel" rows that seem to move even though they are stationary.
