now I'm imagining seeing a primary color for every prime number. Maybe Geordi LaForge sees that way, but I don't think anyone else does.
(There are some species of mantis shrimp which are thought to have up to 16 different color sensing pigments in their eyes, which might mean they see in 16 different primary colors, compared to the 4 primary colors that is typical for most arthropods and most non-mammalian vertebrates. )
