Is that true, blakey? Why would they do that??
well, am not sure legislation specifically target black people, rather it was aimed at people born outside the uk.
here's some info, taken from wikipedia, if you are actually curious as to what happened -
"Until the Commonwealth Immigrants Act 1962, all Commonwealth citizens could enter and stay in the UK without any restriction. The Act made Citizens of the United Kingdom and Colonies (CUKCs), whose passports were not directly issued by the UK Government (i.e., passports issued by the Governor of a colony or by the Commander of a British protectorate), subject to immigration control.
Enoch Powell gave the famous "Rivers of Blood" speech on 20 April 1968 in which he warned his audience of what he believed would be the consequences of continued unchecked immigration from the Commonwealth to Britain. Opposition Leader Edward Heath sacked Powell from his Shadow Cabinet the day after the speech, and he never held another senior political post. Powell received 110,000 letters – only 2,300 disapproving-[27] as a result of the speech and a Gallup poll at the end of April showed that 74% of those asked agreed with his speech.[citation needed] After the 'Rivers of Blood' speech, Powell was transformed into a national public figure and won huge support across Britain.[citation needed] Three days after the speech, on 23 April, as the Race Relations Bill was being debated in the House of Commons, around 2,000 dockers walked off the job to march on Westminster protesting against Powell's dismissal,[28] and the next day 400 meat porters from Smithfield market handed in a 92-page petition in support of Powell.[29]
By 1972, only holders of work permits, or people with parents or grandparents born in the UK could gain entry – significantly reducing primary immigration from Commonwealth countries.[17]
The British Nationality Act 1981, which was enacted in 1983, distinguishes between British citizen or British Overseas Territories citizen. It also made a distinction between nationality by descent and nationality other than by descent. Citizens by descent cannot automatically pass on British nationality to a child born outside the United Kingdom or its Overseas Territories (though in some situations the child can be registered as a citizen)."

as to why limits on immigration were put in place i'd mak two points
- after the ww2 britain needed new workers, so we asked for & welcomed many immigrants from the carribean/west indies and indian subcontinent, then when it was thought enough had come the rules were changed to limit immigration
- as per my previous posts, britain was a much more racist country in the past, certainly when you're looking more than 20, 30 or 40 years ago. that being said, however, i think it is possible for countries to want to limit immigration for reasons not solely due to racism
