Optical illusion transforms black and white picture into colour simply if you stare at it. Check it out!
An optical illusion is characterized by visually perceived images that are deceptive or misleading. Therefore, the information gathered by the eye is processed by the brain to give, on the face of it, a percept that does not tally with a physical measurement of the stimulus source. A conventional assumption is that there are physiological illusions that occur naturally and cognitive illusions that can be demonstrated by specific visual tricks that say something more basic about how human perceptual systems work. The human brain constructs a world inside our head based on what it samples from the surrounding environment. However, sometimes it tries to organise this information it thinks best while other times it fills in the gaps.This way in which our brain works is the basis of an illusion.
