Children’s book illustrator Loren Long, whose mother told him immediately after he learned he was colorblind that he should still pursue the art he loved: “In general, I can’t tell the difference between the many shades of brown and green or blue and purple. They’re very similar to me. Light blue and lavender look the same, and tan and pale green are almost impossible to tell apart. My living room is a shade of gray, but if my wife had told me it was green I would have taken her word all these years.”
