Science Explains Why Color Is a Brain Construction, Not an Objective Reality
Neuroscientists assert that color does not exist as an objective property in the physical world but is instead a subjective construction created by the human brain. According to Christof Koch of the Allen Institute for Brain Science, objects reflect photons with specific wavelengths, which the eyes convert into electrical impulses. The brain then interprets these signals to generate the experience of color, a phenomenon known as qualia. This explains why describing color to someone who has never seen it is impossible, as illustrated by the philosophical thought experiment Mary's Room. Perception varies among individuals due to factors like genetics, life experiences, and exposure to different lighting conditions. A notable example is the viral 2015 dress illusion, where people saw either blue and black or white and gold based on how their brains interpreted ambient light. Research by Pascal Wallisch at New York University supports this, linking perceptual differences to habitual exposure to natural or artificial light. Ultimately, the brain builds a coherent visual reality through unconscious calculations, meaning our perception is an interpretation rather than an exact replica of the physical world.
