When regular animals see a rainbow, they're just like "hmm yes, pretty colors" and move on with their day. But scientists? Oh boy. They're over there frantically calculating wavelengths, debating whether it's 380-700 nanometers or 400-700 nanometers of visible spectrum, and getting into heated arguments about tetrachromatic vision in shrimp. The electromagnetic spectrum waits for no one! That seal is blissfully unbothered while the scientists are having an existential crisis about whether magenta is even a real color or just a brain construct. Classic example of the Dunning-Kruger effect in reverse—the more you know, the more you realize how much you don't know!
