An image that has gone viral recently is apparently unique since only 1% of people can find the animal in this picture. Have you tried it yet?

The McCollough effect is a trick on the mind, which, after staring at a colored grating (alternating lines) for several minutes, makes your brain start to see a pinkish tinge or other colors when looking at black-and-white lines.
If you tilt the head 90 degrees, you may reduce or improve the effect, and you can reverse it by rotating the induction images. Also, the longer you look at the original induction images, the longer the effect will last.
This phenomenon, defined as a visual illusion in which retinal impressions persist after the removal of a stimulus, is a sort of afterimage. Researchers believe that it is a result of the continued activation of the visual system. Strong colors make an impression and trick it into thinking that it is still looking at the colors even when it is not, and this eventually makes one believe that what he sees are black and white stripes, tinged with red and green.
The Journal of Experimental Psychology found that in the same way as the bright flash of the camera can linger in the vision, this effect can last for over three months in case the perceiver looks at the colorful gratings for extended periods of time.

This effect has been named after the discoverer, US psychologist Celeste McCollough Howard, who found this so-called “contingent aftereffect”, an illusion that affects your brain for an extended period of time.

span class=”s1″>These two induction images can stimulate the effect if you alternate between staring at their centers for a few minutes.   Afterward, if you look at this image, you will see it red or green in parts or even pinkish.
However, researchers warn that if you don’t see the effect after a few minutes of looking back and forth, you should be careful if you decide to try it for longer.
