We talk about people being “colour-blind” But very few of us are Even those who describe themselves as colour-blind are normally just colour lack. A strongly colour-blind person will still be able to tell 20 different colour, compared to the 100 or so that normal-sighted people see.

Pingelap, a tiny island in the Pacific, is a beautiful spot but one that has a genetic trouble. It is known as Colour-blind Island because so many people who live on this remote island can only see in black and white.

Not being able to see in colour is bad enough. But one islander, Herrol, who’s a fisherman, also struggles in full sunlight because all be sees is a painful burnt-out image. “I find it difficult to go outside in the sun,” he says, “because when it’s sunny I cannot see to do my work.”

But if being truly colour-blind is rare, why is it that around 10% of the population of Pingelap live in a totally black and white world?

Well, we know that in 1780 the population of Pingelap was all but wiped out by a tsunami(海啸). As few as 20 people survived, one of whom was the king. It’s believed he had a genetic fault that causes colour-blindness and he passed this fault on to his many generations.

There is one advantage. Herrol can see well, really well, in the dark. So when it gets dark, Herrol and his fiends get in their boats and hunt flying fish. They hang up flaming torches and die fish are attracted to the flames.“This type of fishing is fun,” Herrol says, “especially if we catch plenty. So even though it’s hard work we enjoy it.”
