Purple Rain Riot was an anti-apartheid protest held in Cape Town on September 2, 1989, four days before South Africa’s racially segregated parliament held its elections. A police water cannon with purple dye was turned on thousands of Mass Democratic Movement supporters who poured into the city in an attempt to march on South Africa’s Parliament. White office blocks adjacent to Greenmarket Square were sprayed purple four stories high as a protester leapt onto the roof of the water cannon vehicle, seized the nozzle and attempted to turn the jet away from the crowds.
