The official seal of the Marine Corps has been in use since 1954 and features the official colors of both the Marine Corps and the Navy. It uses the Marine Corps emblem of the Eagle, Globe and Anchor.
General Lemuel C. Shepherd, Jr. asked to have an official seal designed for the Marine Corps in 1954, and on June 22 of that year, President Dwight D. Eisenhower approved the design. The Marine Corps adopted the seal in 1955.
Scarlet and gold are the official colors of the Marine Corps. A scarlet background and a gold ring surround the Marine Corps emblem in the seal. A blue ring and a gold ring encircle the seal. Blue and gold are the official colors of the Navy, and are used since the Marine Corps is part of the Navy.
The Eagle, Globe and Anchor became the Marine Corps emblem in 1868. The Marine Corps emblem first used an anchor in 1776 and then added an eagle in 1834. The anchor references the Marine Corps association with the Navy and signifies that it the Marines can access any coastline. The eagle represents the United States. The globe represents the world.
The emblem of the British Royal Marines had some influence on the Marine Corps' emblem. The British Royal Marines' emblem features a globe that shows the world's Eastern hemisphere. The globe on the Marine Corps' emblem shows the world's Western hemisphere.
