meaning of colours in the south african flag
Three of the colours -- black, green and yellow -- are found in the flag of the African National Congress. The other three -- red, white and blue -- are used in the modern flag of the Netherlands and the flag of the United Kingdom; the colours white and blue were also found in the old flag of South Africa. Former South African President F.W. de Klerk, who proclaimed the new flag on 20 April 1994, stated in his autobiography, The Last Trek: a New Beginning, that chilli red was chosen instead of plain red (which Anglo-Africans would have preferred) or orange (as Afrikaners would have preferred).
