A scientific tale of two dresses

There is a scientific explanation to why people are seeing two different colors of the now- famous dress. The tiny cones in the back of our eyeballs allow us to recognize colors in a different way depending upon our genes.  Our retinas, the fine layer of nerve tissue that lines the back of our eyes, notice the blue, green, and red in an image. Our brain and the cones mix those colors to make other colors. The top section of the dress is gold to some people, but black to others. A doctor states that the most common color confusions we see are blue and yellow. One theory has to do with evolutionary biology. It is often essential to factor out colors in the light around an object that may give it a different and confusing complexion. Some doctors think that this dress could possibly help advance medical science and hopefully help people with vision problems.
