At some point in his life, Yves Klein decided that, from that moment, he would paint pictures of one color: Blue. But not just any Blue, Yves wanted a unique Blue, his Blue, the Blue Klein! To paint his works Yves used wind, rain, fire, even human bodies, inventing the Body art. He also composed a symphony of a single note and used photography to challenge gravity: he always managed to find new ways to amaze his audience.
