Every so often, an optical illusion goes viral on the Internet and makes us question our own eyes. This week too, a mind-boggling optical illusion is confusing social media users across the globe. This time, it’s making people see colours where there are none!
The optical illusion was posted to Twitter on Saturday by Lionel Page, an economist at UTC Economics, according to the Mirror. It shows a group of people smiling for the camera. While the image is black and white, coloured grid lines have been placed on top of it.
“This is a black and white photograph. Only the lines have colour,” wrote Mr Page while sharing the pic online.
Do you see this image as coloured? Well, that’s because the of the grid lines that trick your brain into thinking the whole picture is coloured.
Here is how people reacted to the optical illusion, which has collected over 18,000 ‘retweets’ and twice as many ‘likes’.
