I was sitting with my three-year-old grandson the other day, coloring with Crayons. It was great fun, and brought back a flood of childhood memories. As I sat there, the names of the colors I loved came back: Cornflower. Red-orange. Burnt orange. Burnt sienna. My mind started to wander, and soon I was deep into curiosity-driven research about colors, how they’re formulated, and how we see them. I discovered some amazing facts. Enjoy the episode.
