The dress is actually blue and black, but why do so many like gold and white? Are they color blind – or?
It is about how one species (humans) perceive colors in a world where light is constantly changing, explains neuro-color researcher Bevil Conway at Wellesley College in the US.
As is known, consist of light of different wavelengths, where each wavelength represents a certain color. The light passing through the lens and strikes the retina at the back of the eye where different neurons convey impulses to the brain which converts them into different colors.
We humans are adapted for a life in the day, but the light of day shifts. From a more pinkish-red in the morning to blue-white at noon and then back to the reddish evening.
According Bevil Conway trying our vision constantly compensate for this shift in the color scale by ignoring certain share it.
Usually it works just fine. But there are individual differences in how our brains choose and sometimes hits the reflected light of an object just “on the border” where we interpret the colors differently.
– Some people ignore the blue side, and then one sees dress white and gold, or ignore the gold side and then the dress is blue and black, says Bevil Conway to Wired.
