Awesome one, 1Ashkent. The ball looks like it’s moving up the board, whether I’m looking directly at it or using peripheral vision.

This is called the Munker-White illusion (or sometimes just the Munker illusion), and it’s a powerful one. When you’re not looking directly at the balls, the color of the stripes pulls the color of the ball toward it, in a manner of speaking, so the green stripes make the ball look greener. These levitating spheres may appear red, purple or green at first glance, but in actuality, all 12 orbs are the same bland shade of beige. Shrinking the image exaggerates this illusion, while zooming in minimizes the effect, according to David Novick, the creator of the image and a professor of engineering education and leadership at the University of Texas at El Paso. But why do we perceive the spheres as anything but their true color, beige? This skewed perception stems from a phenomenon known as the Munker-White illusion, Novick told Live Science. It is only when you look at the entire photo, the spheres assume different colors. Here is that same photo with no stripes going over the spheres. So why is this happening? Why do we see the color of the spheres change even though we know that they are all in the same color? Syfy explains: In a nutshell, we do perceive colors as they stand on their own, but also by contrast with colors around them. If I put up an image of a red square, then (assuming you have normal color vision) it looks red. But if I put up objects with other colors around it, the color we perceive changes a bit. That can be manipulated using stripes of different colors, for example. In the top row, note the colors of the stripes going across the balls. The left one has green stripes, the middle one red, and the right one blue. That changes how we see the balls.
