Look at this close-up image, you can see several pastel shades suddenly disappearing from your field of vision. But explaining optical illusions can be extremely difficult.

It’s always a tall order to explain the intricacies of optical illusions. This image features a pastel color palette that suddenly seems to disappear from your field of vision. The image quickly captured attention and started spreading like wildfire on social media. The drawing appears to go colorless when you stare at it for 2-2 seconds, but the colors reappear as soon as you blink.

According to The Verge magazine, this optical illusion has been around for 214 years. The philosopher Ignaz Paul Vita Troxler was the first to unveil this illusion to the public in 1804.

The Verge explains that the brain ceases to perceive patterns that remain constant and do not change. Under normal conditions, the movement of your eyes and your surroundings provide enough variables to keep your brain alert. In this specific case, however, the patterns are so blurry and still that they eventually disappear from your field of vision. Tell us if you have been sensitive to this phenomenon:

It’s kind of like when your senses go numb, like when you put on your warm socks in the morning, you feel them initially, but as the day progresses, you don’t even notice they’re there. Going through your day without feeling your socks off, or watching that image evaporate before your eyes: which of these experiences do you find craziest?
