Acclaimed German artist Gerhard Richter has created a major new work, 4900 Colours: Version II, for an exhibition at London's Serpentine Gallery.
Richter is widely regarded as one of the world's best living artists. He produced the first of his grid paintings in 1966, in which he replicated colour paint charts on a large scale.
He has produced a varied body of work over the years, including photography-based portraits, landscapes, still life and abstract, as well as his colour-chart grid paintings.
Since 1964, Richter has had more 100 solo exhibitions worldwide, and was the subject of a major touring retrospective in 2002, called Forty Years of Painting.
In 2003, the artist was second on a list of the worlds top-selling living artists, with sales worth £80.9m.
4900 Colours: Version II and the accompanying exhibition can be seen at the Serpentine Gallery, in Kensington Gardens, from 23 September until 16 November.
