I'm thinking a U.S. protectorate; the Federated States of Micronesia maybe? Reasons include: their use of giant stones as money, Emelihter Kihleng, the first Micronesian to publish a book of poems in English, and the largest island of the group, Pohnpei, formerly Ponape, a long since tucked away tropical haven under U.S. indirect control, among whose residents have a very high rate of an extreme form of color blindness known as maskun...and don't forget Nan Madol.
