This article in the digital journal talks about people who, because of a genetic mutation, can see millions more colors than “normal” people. They aren’t exactly Dr. Xavier, but still, pretty darn cool.

scientists have long believed that there are people with four cones who can see a wider range of colors than most of us can detect. These persons are called “tetrachromats,” and can see a hundred million colors. From the perspective of such people, the hues familiar to trichromats fracture further into more subtle shades of differences that have not been given names since most of us are trichromats who cannot see these shades and name them.
