Why are there so many colors?

This episode of But Why, a podcast for curious kids, explores the topic of color. The host, Jane Lindholm, along with guest Kassia St. Clair, author of "The Secret Lives of Color," answer questions from young listeners about where colors come from, how we perceive them, why different animals see colors differently, how colors get their names, and whether white is a color. They also discuss how colors evoke different emotions and how cultural associations with colors can change over time, using the example of pink and blue. The episode emphasizes the subjective and culturally influenced nature of color perception.
