The hybrid of both sculpture and painting is on full display when it comes to German-born artist Imi Knoebel. Although he studied under Joseph Beuys, he developed his own style that borrowed some elements from Kasimir Malevich. Imi Knoebel has spent a long time in the public sphere now, but he has developed his own evolution. While it is true that Knoebel used to believe that the best medium of all was black and white, he changed his use of color after his dear friend Blinky Palermo passed away at just 33 in 1977. He commemorated with a series called "24 Colours for Blinky." Since then, Knoebel has been a man possessed, with experimentation in color being his driving force.
