About the Official State Flag of New Jersey
In 1780, during the Revolutionary war, General George Washington directed that the regiments of the New Jersey Continental Line have a flag of dark blue and buff (buff and Jersey blue are now recognized as the official state colors of New Jersey).
General Washington presumably selected these colors for historic reasons; New York and New Jersey were both originally settled by the Dutch, and dark blue (Jersey blue) and buff were Holland’s (the Netherlands) insignia. The center of the flag features New Jersey’s coat of arms (featured on the great seal of New Jersey).
