Julia Stockton Rush (Mrs. Benjamin Rush), 1776

In the fall of 1775 Congress chose brown as the original color for the national uniform. In October 1778, however, France sent uniforms with a predominance of blue coats (although there were also brown), and so on 2 October 1779 Congress switched to blue as the official color.
