This podcast episode explores the nature of color perception, from Isaac Newton's discovery that colors are properties of prisms rather than intrinsic to light itself, to the unique vision of animals like mantis shrimps and the potential for curing color blindness in humans. The conversation also delves into the concept of tetrachromacy, where some individuals possess an extra cone in their eyes, allowing them to perceive a wider range of colors. The episode highlights the complexity of color perception and its relationship with language, culture, and individual sensory capabilities.
