INTRO: 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. In essence, the illusion works because "our acuity for shape is better than our acuity for color, which means that we perceive the shapes with more detail and the colors with less detail," Novick said.
So, while the outlines of the spheres all appear identical, as they are, "the color sort of bleeds over, or assimilates, to adjacent spaces," Novick said. Specifically, the color of the spheres gets "pulled" closer to the color of the stripes crossing over them, in the foreground. In this particular image, called "Confetti Spheres 5," an array of green, red and blue stripes cut across the spheres and warp our perception of their actual hue.
The illusion relies on the hue of the foreground stripes, not the colors in the background behind the spheres. So, if you remove the crisscrossing stripes, the illusion disappears, leaving only identical beige balls... (MORE)
