Are you a Tetrachromat?
And what would it mean, to see colors no one else can?
I recently listened to a fascinating Radiolab episode all about color. I was particularly struck by the section on tetrachromacy, which is the possibility that there are superhumans among us who can see more colors than the rest of us.
As you may remember from biology class, we get color vision thanks to the cone cells in our eyes. Humans are trichromats, meaning that we have three types of cone cells: red, green, and blue. These cells allow us to see all the colors that we do. They respond to light within a particular section of the spectrum.
