A mind-boggling optical illusion recently shared on Twitter has gone viral after leaving thousands doubting their senses.
Created by University of Texas academic, Professor David Novick, the ‘Confetti’ illusion features 12 coloured dots and multi colored horizontal lines.
On first view the dots appear to be different colours when viewed from afar but up close they are visibly all the same colour.
A new Munker illusion, which I call confetti. All the dots in the background are the same color (RGB 250, 219, 172) but are perceived as four different colors. The differences are subtle, though, and depend on the size of the image when it’s viewed. cc @AkiyoshiKitaoka pic.twitter.com/vT6x64LLTy

The illusion is an example of the Munker Illusion – a type of illusion that affects how the brain sees colour based on which colours surround them.
Professor Novick explained: “A new Munker illusion, which I call confetti.”
“All the dots in the background are the same color (RGB 250, 219, 172) but are perceived as four different colors.
“The differences are subtle, though, and depend on the size of the image when it’s viewed.”
“I didn’t want to believe it”
Professor Novick’s baffling illusion was originally shared on Twitter and has since been retweeted 6,400 times and liked over 17,000 times.
Many users have taken to the platform to voice their confusion.
That’s terrific! When I zoomed in I could see they were the same colour, but even knowing this I can’t ‘see’ it when the picture is small.

When I take a screen grab of the image and open it in GIMP, the colour picker shows them as being different. Is this an artefact of copying the image?

I didn’t want to believe it till I zoomed in! Crazy

Although I read your explanation, my mind still refused to belive it until I zoomed in.

Crazy how the color changes when the image gets bigger.
