In this conversation, Sean and Jon delve into the fascinating world of color perception, discussing a recent scientific breakthrough that allows individuals to perceive a new color named Olo. They explore the underlying science of how color is perceived through the eyes and brain, the physics of light, and the differences in color perception among various species. The discussion also touches on the implications of color blindness and the common misconceptions surrounding it, emphasizing the brain's role in interpreting visual information. Jon teaches Sean about the complexities of color vision, discussing various types of color deficiencies, the rarity of true color blindness, and the implications of color vision in everyday life and certain professions. They explore the mechanisms of night vision, the philosophical perspectives on vision from ancient thinkers like Plato, and how our understanding of light and color has evolved over time. The discussion highlights the fascinating interplay between biology, perception, and the environment in shaping our visual experiences.
