suppose you’re at a concert with a friend who leans over and whispers in your ear, “What color was that music?” It may seem like a strange question, but there are some people for whom the answer is entirely self-evident, and perhaps your friend is among them. Such individuals have a neurological condition called “sound-to-color synesthesia,” or “chromesthesia,” in which they effortlessly and spontaneously experience their own personal light show while hearing music and other sounds.1 Interestingly, many chromesthetes grow up assuming that everyone has the same visual responses to sounds as they do, and are shocked when they discover this is not so?
