The Unions colors are navy blue and gold, representing the primary colors of the Continental Army's uniforms during the American Revolutionary War. The team's crest is circular, symbolizing unity. Its thirteen gold stars represent the original Thirteen Colonies, while the shield's contour derives from the Philadelphia coat of arms. The rattlesnake represents the "Join or Die" political cartoon by Benjamin Franklin. The light blue in the middle of the crest is a tribute to the Sons of Ben.
