WHAT are the colours of the Easter eggs in this optical illusion?
Orange? Pink? Orange? Green?
What if we told you they were all the same colour.
The mind-blowing image is officially called a Munker illusion and it tricks your eyes in a very clever way.
Basically, the tight lines deceive our brains into seeing different colours.
Professor David Novick, who creates all sorts of optical illusions, has posted several just like it on Twitter.
“The illusion is a function of the foreground framing color, which tends to tint the central circle,” he previously explained.
“The apparent color of the central circle is a mix of the foreground framing color and the circle’s color.”
The more you step away, the more the effect works too.
If you don’t believe it, there’s a way to check yourself.
