If a painting has only one colour, this colour will become the determining motif. If the colour covers the entire surface of the painting and if, in addition, the painting's format is conceived as an element to be freely fashioned, the real wall has been declared to be the painting's proper ground.
The German artist, Imi Knoebel, who was born in Dessau in 1940, creates painting-objects made of hard fibre or aluminium that seem to hover before the wall in freely contoured geometrical forms. Radically non-representational and reduced to the artistic principles of form and colour, his paintings nevertheless have a sensual effect. In large formats, the flat wall-sculptures possess a monumental presence whilst simultaneously hovering weightlessly.
