From BBC - Future:
As Concetta Antico took her pupils to the park for an art lesson, she would often question them about the many shades she saw flashing before her eyes. … Today, she knows that this is a symptom of a condition known as “tetrachromacy”. … Tetrachromats are rare enough, but Antico is particularly remarkable, since, as an artist, she is able to give us a rare view into that world. “Her artwork might tap into a structure that all of us can appreciate,” says Kimberly Jameson at the University of California, Irvine, who has studied Antico extensively. It’s even possible that she might suggest ways for more people to see the same way.
