Bridget Riley: Circles Colour Structure : Studies 1970/71

Bringing together over 20 gouache studies by the celebrated British Op artist Bridget Riley, this exhibition catalogue reveals something of Riley's process. Originally published to accompany an exhibition at Karsten Schubert, London, the studies explore the results of Riley setting circles of colours - such as turquoise, cerise and ochre - at different distances.

The images are accompanied by an interview with the artist by Robert Kudielka from 1972, just following the creation of these works.

In the discussion, Riley touches upon the role of her studies and the effects of her colour choices on light and movement in the picture plane.
