To experience the visual adventure for yourself, take a moment to look at the blur of colors in the image above, and then stare at the center of it. Specifically, stare directly at the center for about 10 to 20 seconds. Did anything weird happen? Did the colors in front of you vanish? Yeah... It's bonkers.
Evidently, this happens because of something called Troxler Fading, a phenomenon that affects visual perception when a person fixates on a particular point. Basically, it causes the surrounding area outside the fixation point to fade away and disappear as your brain "fills in" in the area with whatever color is in the background. It's wild, but hey, so is the human brain.
