Le Rose du Bleu (RE 22), in English: The Pink of Blue (RE 22), is a painting created by French artist Yves Klein, in 1960.
This trilogy could be interpreted as having a religious symbology, similar to the Christian concept of the Trinity.
Madder rose represents the Holy Spirit before the gold of the Father and the blue of the Son; gold for immortality and blue for sensibility..."[2] For creating La Rose du Bleu (RE 22), Klein used dry pigment and synthetic resin of the pink and blue colours, combined with the natural elements of marine sponges and pebbles, on a panel.
Paul Nyzam, in the Yves Klein website states: "With their absorptive and highly material 'living' sponges affixed to a monochrome plane of colour, Klein's sponge-reliefs are the quintessential (ultramarine International Klein Blue) but within the context of Klein's spiritual trinity of colour, the corporeal, material colour of rose or pink, became, as the title of RE 022 directly suggests, as appropriate a colour, if not indeed a more fitting one, than the blue.
"[4] The painting was the most expensive by the artist sold in the art market when it reached £23,561,250 ($36,753,200), at Christie's London, on 27 June 2012.
