Why some members of Congress are wearing yellow roses today

Gold is one of three colors of the American suffrage movement — along with white and purple, which helped give it instant visual recognition.

Today, some members of the U.S. Congress are wearing yellow roses to mark 100 years since the House of Representatives voted to pass women's suffrage. The right for women to vote became law in 1920.

The gold color represents light and life. It is "the torch that guides our purpose, pure and unswerving," reads "The Suffragist" regarding the gold color. The book was published in 1913.

The color purple was chosen for loyalty and steadfastness. The white was selected as an emblem of purity.

National organizations and state and local groups will be hosting Women's Suffrage Centennial events in 2020 to mark 100 years since the women's right to vote became law. Go here to read more about the 2020 Women's Vote Centennial Initiative.
