Nobody in the world sees things the same way. Everyone has their own perspective on what things are and what they look like. Recently, a new photographic phenomenon - the dress - has spread across social media all over the world, baffling viewers everywhere. People everywhere are disputing the colors of this dress, and asking, “Is it blue and black? Is it white and gold?” The truth is, however, that the dress is in fact black and blue. Now, many of you may be wondering, why do some people see white and gold, why do some see black and blue, and why do some even see other colors.
There is a scientific logic to all of this madness, relating to how your eyes perceive things. Over the course of many millennia, humans have evolved to have different types and amounts of color (cone) cells implemented in their eyes. People with four types of cone cells are called tetrachromats. These types of people see all of the colors of the spectrum clearly, and therefore, would most likely see the dress as blue and black, the correct colors. Only twenty-five percent of the population consists of people with this kind of vision, explaining how not everyone saw the actual colors of the dress.
On the other hand, fifty percent of our population has trichromatic vision.This means that they can only see mixtures of three colors. This correlates to the fact that they do not see every color of the spectrum, so they could see the dress either way. Similarly to this type of vision, dichromats could see the dress incorrectly as well. These dichromats have two types of cone cells, and can see a mixture of only two colors on the visible spectrum. People with this type of vision make up the final twenty-five percent of the Earth’s population.
