YOUR BRAIN’S DRESS CODE How could one dress capture the world’s attention? In 2015, a woman took a picture of a dress she planned to wear to a wedding. What began as a social networking post became a global sensation, leading millions to wonder: What color is the dress? Although the dress is actually blue and black, a brain imaging study of 1400 people showed that 43 percent saw the dress as either white and gold, blue and brown, or blue and gold (Lafer-Sousa et al., 2015). These perceptions show how people differ in how they process color information (Schlaffke et al., 2015).
