Not really — it’s a buzzword and a scam. But at least it provoked this very good summary of color vision and color blindness in response to an absurd claim by a neuromarketer.
It’s a solid response to the claim that 25% of people are tetrachromats…although I’d never heard such an extravagant number before. Tetrachromats — people who effectively have four different functional classes of cones in their retina — are incredibly rare, exist largely in the domain of a theoretical possibility, and have been demonstrated only a couple of times. It takes some chutzpah to argue that they’re ubiquitous!
