How were women of color affected by passage of the 19th amendment?

Back when I was a member of the Business and Professional Women, I learned a lot about the women's suffrage movement and the passage of the 19th Amendment. What we didn't learn a lot about is the role of Women of Color in the movement, or the fact that their voting rights were delayed even longer than 1920. So that was what I asked Cokie Roberts on NPR's Morning Edition.
