The original blue shade of Micronesia's flag was based on which organization's flag?

The original blue shade of Micronesia’s flag was based on the flag of the United Nations. The shade first appeared on the flag of the Trust Territory of the Pacific Islands, the U.S.-administered trust territory from which the Federated States of Micronesia emerged.

The Trust Territory adopted its first flag on 24 October 1962. Its blue field drew inspiration from the United Nations flag, while six white stars represented the territory’s districts. Gonzalo Santos designed that flag, which was officially approved in 1965.

When the Federated States of Micronesia adopted a four-star version on 30 November 1978, it retained the trust territory’s blue-and-stars concept. The four stars represent Chuuk, Kosrae, Pohnpei, and Yap, the FSM’s four states, rather than the six districts of the earlier design.

A common mix-up is confusing the flag’s historical color inspiration with its symbolism. The blue field is also described as representing the Pacific Ocean, but the question asks specifically what organization’s flag inspired the original shade: the United Nations. The FSM later replaced that lighter shade with a darker blue in 1986.
