Stuart Hall argues in the documentary “Race -The Floating Signifier” that race is a signifier which has meaning in a culture, but the meaning of skin colour is not fixed. The significance and social viewpoint of skin colour changes between different cultures. In addition, the meaning of skin colour slides and floats on the scale of interpretation held by members of a society. (Hall, Stuart. Race the floatingsignifier)
Below I will support the theory of Hall and show in the historical context that has emerged as "Race" and how this concept changes over time.
