A MIND-blowing optical illusion shows how our brains lie to us.
Using a traffic light and a cyan filter, TikTok user beatonthebeeb explains the illusion and the trick our brain is playing on us.
The user, who also goes by the name Dean Jackson, starts by showing a regular stoplight with the typical green, yellow, and red colored lights.
He then adds a cyan filter over the traffic light, saying that red specifically cannot pass through this filter.
“Yet you’re still seeing the red light, right,” he asks.
“I can guarantee you that there is no red light there at all,” he says.
“There’s no red at all!”
Jackson then goes onto explain how our brains are playing a trick on us and offers proof to back up his claim.

“It’s your brain working overtime convincing you of the red,” he says.
In an attempt to prove the illusion, Jackson then covers the non-red lights with the color gray.
“Now look … it was grey all along,” Jackson says.
The video has been viewed more than 16million times and has amassed more than 1.8million likes.
In a follow-up video, Jackson again turns to the same traffic lights for a similar optical illusion.
In this case, he uses a different filter to show that yellow light is not, in fact, passing through, and is gray.
