Yves Klein

                                          Accord Bleu, 1958, sponge relief on particle board

Anthropometrie de l'epoque blue, 1960, 156 x 256 cm

Accord Bleu, the signature piece of Klein, absorbs the viewer into its sea of blueness.  Form and shadow created by the sponge reaches out to viewers.  Texture of the sponge creates shadow and depth.  The blue color, patented to belong to Klein, is called IKB - International Klein Blue.  From this starting point Klein progressed to the Anthropometrie.  Performance art combines with minimalist art as models pressed their paint covered  bodies into canvas.
Romantic and mystical ideas express in the works of Klein.  He restricted his work to monochrome blue, patented his specific color and felt that the only way he wanted to express himself was through color.
