THE SCIENCE OF WHY THE DRESS CHANGES COLOR. Adam Rogers explains the shifts in the colors of the controversial dress in terms of the adjustments which our brain makes to the information that the eyes give it. Our eyes have evolved to make adjustments to the signals from the eye to take account of the surrounding light. The brain corrects for the background light which can vary during the day “from the pinkish red of dawn, up through the blue-white of noontime, and then back down to reddish twilight”. The brain will adjust so that the object will seem to have the same “real” color, whatever the conditions of light. Apparently this dress dramatizes differences in the way that the corrective process operates in different people and in different conditions
