And then, most amazingly, there are the very rare people who are born with the ability to see this world of new colors that the rest of us can’t even imagine. These people are called tetrachromats, because they have four cones in their eyes instead of three like the rest of us. Each cone is responsible for seeing about 100 shades, so for us normal folk, that’s about a million colors. But for tetrachromats? They see a hundred million colors.
