Concept
The flag of the United Nations consists of the emblem depicting the white azimuthal equidistant projection of the world map, centred on the North Pole, with two white olive branches placed on to its right and left, located on the sky blue background. The emblem was officially adopted on 7 December 1946, and the flag, on 20 October 1947. The flag of the United Nations consists of the white emblem on the sky blue background. The emblem depicts a azimuthal equidistant projection of the world map, centred on the North Pole, with the globe being bisected in the centre by the Prime meridian and the International Date Line, thus ensuring that no country is at prominence within the flag. The projection of the map extends to 60 degrees south latitude, and includes five concentric circles. The map is inscribed in a wreath consisting of crossed conventionalized branches of the olive tree. The size of the emblem on the flag is one half the width of the flag itself. The flag proportions of the aspect ratio of the flag height to its width, are equal 2:3, 3:5 or to the same proportions as the national flag of any country in which the UN flag is flown. White and blue are the official colours of the United Nations. The light blue background colour code is Pantone Matching System 2925. It approximates sky blue. The olive branches are a symbol for peace, and the world map represents all the people and the countries of the world. The organizers of the 1945 United Nations Conference on International Organization in San Francisco, California wanted an insignia that could be made into a pin to identify delegates. United States Secretary of State Edward Stettinius, Jr. was chairperson of the U.S. delegation, and realized that a temporary design might become the permanent symbol of the United Nations. He formed a committee headed by Oliver Lundquist that developed a design consisting of a world map surrounded by leaves from a design created by Donal McLaughlin. McLaughlin had previously worked as chief of graphics for the Office of Strategic Services that preceded the CIA.
