Book excerpt: This is the first book by an author in the UK to take an in-depth look at colourism - the process of discrimination based on skin tone among members of the same ethnic group, whereby lighter skin is more valued than darker complexions. The African Diaspora in Britain is examined as part of a global black community with shared experiences of slavery, colonization and neo-colonialism. The author traces the evolution of colourism within African descendant communities in the USA, Jamaica, Latin America and the UK from a historical and political perspective and examines its present impact on the global African Diaspora. This book is essential reading for educators and students and will appeal to anyone with an interest in the subject of race and identity who wants to understand why colourism - a psychological legacy of slavery still impacts people of African descent in the Diaspora today.
