Adopted on July 24, 1913, the Delaware state flag has a background of colonial blue surrounding a diamond of buff color in which the coat of arms of the state is placed. Below the diamond are the words "December 7, 1787," indicating the day on which Delaware was the first state to ratify the United States constitution. Because of this action, Delaware became the first state in the Union, and is, therefore, accorded the first position in such national events as presidential inaugurations. According to members of the original commission established to design the flag, the shades of buff and colonial blue represent those of the uniform of General George Washington.
