这些球的颜色都是一样的

If there’s one thing optical* illusions* make clear, it’s that perception is not always reality, which is why in the case of one viral* image, what’s visibly green, red or blue is actually light brown.

In a tweet from David Novick, a professor of engineering education and leadership at the University of Texas in the United States, an image shows seemingly different-colored spheres floating amid streaks of red, blue and green lines.

The orbs are actually all the same color. “A three-color confetti* illusion with spheres, which appear to be yellow, red, and purple but in fact have exactly the same light-brown base color,” he writes.

Colors perceived by human vision take into account not just the color of the object one is looking at, but the colors that surround it as well.

The optical phenomenon* is known as the Munker-White illusion and describes the process of the human brain organizing colorful information based on their luminance*.

Among the most famous examples of the power of sensory* illusions is what is commonly referred to as “The Dress” — a piece of clothing that appeared either blue and black or white and gold depending on the observer. In an auditory* puzzle known as “Yanny and Laurel,” listeners are tasked with discerning whether a voice in a recording is uttering “Yanny” or “Laurel.” The answer is both.(SD-Agencies)
