For my second post I wanted to talk about the dress! This dress is very well known over the internet because people see different colors. Its either Black and Blue or White and Gold. When I look at the dress I see White and Gold, but its actually Black and Blue. The way you see things is how your brain processes color. Light bounces off objects in the world and then reaches your eye in wavelengths which signals your brain to interpret color. Pascal Wallisch explained, "this mix depends on two things: the color of the object and the color of the light source. To achieve what color vision scientists call 'color constancy,' the brain calculates color-corrections for an image on the fly. It takes note of the illuminating light and tries to figure out how it might be affecting the color of an object." The dress was taken in different lighting with bluish tint, your brain sees it as white and gold or black and blue.
