My mother recalls seeing the ‘no coloureds’ notices as a child in newsagents and sweet shops. Often they were written on the backs of envelopes; sometimes they were placed on removable boards outside. She used to read them when she was queueing with her sister for sherbet lemons in the postwar sugar rush. They didn’t deter her, on the brink of the 1960s, from marrying my Sri Lankan father. He docked at Tilbury in June 1953, when he was 22. He saw the ads not in sweet shops but at railway stations, on the noticeboards next to the telephones and ticket offices at Greenford, Ealing Broadway and West Ruislip, where British Rail gave him his first job as a ticket collector. One landlady, he told me, asked him to describe the precise colour of his skin: how did it compare to a cup of coffee, for example? She was pleased to establish he was ‘not black but brown’, someone who could be accommodated as part of a wider system of exclusion.
