The main color of the United Nations flag is light blue. The flag features a world map, depicted in white, centered on a blue background, symbolizing peace and unity. The blue color is intended to represent a sense of hope and the desire for tranquility among the nations. The emblem also includes olive branches, which are symbols of peace. The flag was officially adopted in 1946, shortly after the establishment of the United Nations, and has since become a recognizable symbol of international cooperation and the promotion of human rights around the globe.
