Suffrage flag, undated, ca. 1913. Gift of the Susan B. Anthony Center, University of Rochester.
While gold was the only color used by all US suffrage organizations (though white also became widely adopted once parades started), the purple, white, and gold combination was used only by the National Woman’s Party in the United States. The organization described the meaning of these colors in a newsletter published December 6, 1913: “Purple is the color of loyalty, constancy to purpose, unswerving steadfastness to a cause. White, the emblem of purity, symbolizes the quality of our purpose; and gold, the color of light and life, is as the torch that guides our purpose, pure and unswerving.”
