What colour are these circles? Optical illusion leaves internet baffled

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.

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.
