The Internet did not have time to calm down after the hype around either a white-gold or a blue-black dress, as a new task appeared: what color are these shoes? Looking at the varnishes, you understand that they are different, but he and the other color seems to be the same with shoes. How so?
Netizens are beginning to actively discuss and push versions. None of the scientists have yet commented on this phenomenon. But perhaps the explanation is the same as in the case of the dress.
So, the thing is how the human eye works. If you remember from a biology school course, the retina consists of two types of photoreceptors - cones and rods. The first are responsible for the perception of color, and the second - for light and form. Simply put, at dusk we see the world with chopsticks rather than cones. And depending on which photoreceptors are more in a particular person, and how the subject is illuminated, this is how we see it.
And yet: the rods work thanks to the pigment rhodopsin, which is very sensitive to light of low intensity and is destroyed when exposed to bright light. He needs about 45 minutes to recover.That is why we are so hard to get used to a dramatic change in lighting. And therefore, if a person looks at a dress in bright light, then leaves for half an hour in a dark room and returns, then, most likely, the color of the dress will change for him.
Moreover, the perception of color is influenced by the way our brain tries to adjust colors and light in order to figure out what color the object really is. In this case, different people either ignore the blue shades, perceiving the image as white and gold, or ignore the yellow shades, seeing a blue-black dress.
