Why We See Different Colors

In 2015, a viral photo of a dress divided the world because people fundamentally disagreed on its color. This phenomenon proved that our brains do not record light accurately, but instead guess colors based on ambient surroundings.

The brain automatically subtracts colors from the lighting in a scene to understand what it is seeing. If your brain assumes the dress is in a shadow, it interprets the colors one way, but if it thinks the dress is under bright light, it sees something else entirely. This disagreement happens because every individual perceives light and shadow contexts differently based on their past experiences. Scientists used this debate to unlock new secrets about how our eyes and minds interpret the physical world.
