While some optical illusions can trick our brains into seeing motion, like the tunnel at Wonderworks, other illusions can trick our brains into thinking that they see different colors. A color illusion takes advantage of something called the “afterimage” effect on the retina. The cones in the back of the retina are desensitized to color after a certain length of staring time, and then when the image is viewed again, even in black and white, the brain projects color into what it sees. This type of color illusion, where our brain projects color into a picture after intentional exposure to the same image in color, is called the McCollough Effect.
Truth is always powerful. We have the following notion 'Truth is always bitter' in certain situations you have to agree. Better go for reality rather than colorful illusions..
''Light is meaningful only in relation to darkness, and truth presupposes error. It is these mingled opposites which people our life, which make it pungent, intoxicating. We only exist in terms of this conflict, in the zone where black and white clash.''
