Bridget Riley (b. 1931)

"I had to give visual sensation more rein--my black-and-white paintings had been about states of being, states of composure and disturbance, but when I introduced colour in 1967 this began to change. Colour inevitably leads you to the world outside…" (B. Riley quoted by P. Moorhouse,A Dialogue with Sensation: The Art of Bridget Riley, Bridget Riley, Tate Britain, London, 2003. p. 19).
