Did you take a good look at the drawing - which consists of a rectangle containing a sequence of stripes in four different colors and twelve acorns? And speaking of color, can you tell what the tones of the circles are? See the image again:

What is the color?

If your guess was that the acorns are all in pastel colors, such as pink, green, yellow and white, we at Mega Curioso would like to inform you that, in fact, the design is an optical illusion created. by an engineering professor named David Novick, and all the circles are exactly the same color. Check out the original illusion:

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

According to the folks at Twited Sifter, the optical illusion above is known as the "Munker Illusion" type - and is characterized by colored stripes that mess up our perception of color and opacity. More specifically, the exact tone of the circles is RGB 250, 219, 172, and if you don't believe us, just increase the size of the image and compare the acorns.

By the way, the Japanese psychologist Akiyoshi Kitaoka - which we already talked about here in Mega Curious precisely because of the optical illusions that he develops, as you can find in this link and here - created a version of the image with hearts, and the result It's almost more impressive.
