Black: the cultural and historical meaning of the darkest colour. From the 'little black dress' which epitomises chic, to its links to death, depression and evil, 'black' embodies many contrasting values. White Europeans exploited the negative associations of 'black' in enslaving millions of Africans whilst artists & designers have endlessly deployed the colour in their creative work. Laurie Taylor talks to John Harvey, Life Fellow of Emmanuel College, Cambridge, about his new book which explores how 'black' came to have such ambiguous and varied meanings. They're joined by Bidisha, the writer and broadcaster.

Also, the last 20 years has seen a major growth in the number of people of mixed racial heritage. Miri Song, Professor of Sociology at the University of Kent, talks about her research into the ways that multiracial parents with white partners talk to their their children about race and identity.
