In Episode 106 (In Between) of Mr. Robin's Hood Podcast hosts Robin Hohweiler (Mr. Robin) and Mikel Mauree Robinson (Mikey) explore the odd idea that some people may possess a fourth color receptor — a condition known as tetrachromacy. They mix personal colorblind (Mr. Robin) anecdotes with science about cones, genetics, and how the brain shapes perception. The episode covers genetic evidence, a lab study finding one likely tetrachromat, and efforts to design tests and even printers that might reveal colors most people can’t see. It’s a curious, funny, and approachable look at what color is and how reality can differ between minds.
