Malcolm Payne: Colour Test For this work Payne used an enlarged, screen-printed facsimile of his personal identity card - a readymade, encoded document. The only change to the document is that where his photograph would usually be, he has substituted a replica of the standard test for colour-blindness. The ID card in itself is an icon of Apartheid charged with emotion. Even without the regulation photograph of the bearer of the card, the 'colour' of the bearer is revealed in a printed code. By putting the colour-blindness test on the ID card, he has instantly created a metaphor, and the whole work becomes a comment on the issue of identity in South African society.
