Over a period of eight centuries, the flourished under an elaborate system of hereditary kings, oral culture, and mythology that kept the population of nearly 1,000 thriving.

Then, in 1775, everything changed. Typhoon Lengkiekie swept across Pingelap decimating the island nation. Of the estimated 20 survivors was the king. Of great fortune to the tribe was their extreme fertility. Within a few decades, the population was approaching 100, but with this came the continuation of a genetic condition of the king. He carried the achromatospia-gen; he was colorblind—and soon, so were many people on the tiny atoll.

In Pingelap, an estimated 5% of the population of 700 are colorblind, whereas the figures are closer to an estimated 1 in 30,000 anywhere else on earth. The phenomenon was first documented by neurologist and writer Oliver Sacks, who set up a clinic in a one-room island dispensary, where islanders described their colorless world in terms of light and shadow, pattern and tone, transforming their history into the book The Island of the Colorblind (A.A. Knopf, 1997).
