Last year, social network users also argued about a photo of a dress in blue or yellow-white. The reason each person sees different colors is due to optical illusion. The human brain determines color by capturing all light from the object and "removing" light from surrounding objects, ie the color of the object is recognized in relation to the color of the object. objects surrounding it.
