THIS thought-provoking optical illusion plays a trick on your mind by making you see color in black and white.
Optical illusions often use color to confuse the human brain, and a TikTok user with the hashtag @hecticNick recently demonstrated this.

Nick shows two images that illustrate how an optical illusion can trick your brain into thinking that a black and white image is color.
First, the content creator shared an image of a building complex in shades of neon blue, orange, and purple.
There is a black dot in the center of the image that TikToker asks users to focus on.
“Keep your eyes on this black dot, do it for about ten seconds,” Nick said in the 17-second clip.
Soon after, the image changes from an oversaturated image to black and white.
However, if viewers looked at the black dot as indicated, the image would appear in color for a moment.
“Look what happens as it changes now. This image is black and white, but I bet you saw some color when it changed,” Nick said.
Many of her 3.9 million followers were stunned, with several thousand taking to the comments section to express their thoughts.
“I saw color but when I looked away it was black and white,” one TikTok user wrote, adding a series of ‘shocked’ emojis.
“Wow, it worked! But how,” another confused user chimed in.
“Wow dude, nice illusion,” commented a third TikToker.
Since it was posted just over a month ago, the optical illusion video has garnered more than 100,000 likes.
How does it work?
The reason this optical illusion works may be because our brain fills in black and white images based on our memory of what the color should be, according to a study.
“Our brains do a good job of keeping colors constant for us,” Pete Etchells wrote for The Guardian.
“When we look at a banana, for example, it will look yellow regardless of the conditions in which we look at it,” he added.
This is known as ‘cortical colouring’ and it occurs via the visual cortex, which is located in the occipital lobe of our brain.
