Oliver Sacks is a physician, best-selling author, and professor of neurology and psychiatry at Columbia University Medical Center. In 1997 Dr. Sacks wrote a book about tiny Pacific atoll of Pingelap, where the genetic disease of complete color blindness (achromatopsia) is much more common than in the rest of the world.

One year after that BBC made a four-part documentary including the Island of the Colorblind. Hereafter you can watch this video, which is split into six smaller parts.

Watching this documentary you can learn a lot about color vision, how it feels to live with complete color blindness and of course a lot about the people from Pingelap.
