Blue

scholar Imani Perry about her new book, "Black In Blues." It's a fascinating meditation on the color blue and how it is intertwined with the concept of Blackness from the dying of indigo cloths in West Africa to Louis Armstrong's question, what did I do to be so black-and-blue? Imani Perry is the National Book Award-winning author of "South To America," as well as several other books including "Looking For Lorraine," which is a biography of the playwright Lorraine Hansberry, and "Breathe: A Letter To My Sons."
