Yves Klein was a French avant-garde artist, a member of the Nouveaux Réalistes, and a pioneer of Pop Art. Klein became known particularly through his monochrome compositions, the 'Monochromes', painted in an ultramarine blue ('International Klein Blue') that he developed himself and patented. The inimitable attractive force of these paintings reflects Klein's mystical Christian attitude and his serene, meditative way of working. His mature work became increasingly dematerialised.
