“Painting doesn’t follow the rules of architectural space; it has a totally different set of rules. Why should it then behave exactly according to those rules?” This is the question that German artist Katharina Grosse asks herself as she creates her colorful explosions over earth, objects and canvas. Her works, previously covered here, are raw and produced quickly with little else besides the artist’s spray gun. The way that Grosse arranges colors has been recently studied in Gagosian Gallery of London’s massive survey of Spray Art. Whether she is creating an outdoor installation or painting on canvas, all of her pieces are site specific, as in her latest exhibition, “The Smoking Kid,” which closed over the weekend at König Gallerie in Berlin.
