AN optical illusion has gone viral after leading many to believe they are seeing a color that isn’t there.
Most optical illusions use color to confuse the human brain.
And a Japanese psychologist proves it after creating a mind-blowing color illusion.
Akiyoshi Kitaoka from Ritsumeikan University in Japan recently shared one tweet an image of a strawberry cake that has confused many.
For the illusion, the psychologist swapped the strawberry’s red pixels for gray ones.
Despite the lack of red pixels in the image, many Twitter users insisted there were.
Disputes soon began brewing under the Twitter thread, with many arguing for the colors they thought they saw.
“There are definitely red pixels,” commented one user.
“It’s a warm grey,” argued another in response.
However, Kitaoka cleared up the debate, tweeting, “Strawberries appear to be reddish even though all pixels are cyan or gray.”
How does this work?
The reason most color optical illusions work may be because our brain fills in images based on our memory of the color, according to a study.
“Our brains do a pretty good job of keeping colors constant for us,” wrote Pete Etchells for The Guardian.
“For example, if we look at a banana, it looks yellow regardless of the conditions under which we look at it,” he added.
This is called “cortical staining” and happens via the visual cortex, which is located in the occipital lobe of our brain.
Another phenomenon behind optical illusions that use color is called color constancy.
“This happens because our brains recognize the color of things by ignoring the color of the light source,” Juno Kim of the University of New South Wales told ScienceAlert.
And in the case of the strawberries, “our brain processes all of this information to account for the lighting and essentially sees red,” Kim said.
“This phenomenon gives us the ability to see colors in changing light conditions, such as B. outdoors or indoors, to be seen almost invariably.”
