The play’s the thing | 9 August 2018

Nothing was so interesting to Yves Klein as the void. In 1960 he leapt into it for a photograph — back arched, chin raised, spread-eagled. The same year, he took out a patent for International Klein Blue (IKB), a colour inspired by the limitlessness of the sky itself. He even went so far as to stage an exhibition of white walls and an empty cabinet. If there is a less appropriate place to exhibit his work than the lavishly adorned Blenheim Palace, I can’t think of it.

Klein was born in Nice in 1928 and learned judo as well as art. In his late teens he visited the Scrovegni Chapel in Padua and marvelled at Giotto’s 14th-century frescoes, particularly the ceiling, which was bluer than the deepest seas. When Klein went on to formulate his own colour in the 1950s, he retained the intensity of the pigment by ingeniously combining it with an artificial resin and petroleum rather than simply oil.
