Color and form coalesce without any representational theme into a single visual experience that nevertheless allows for multifaceted associations. In this respect, geometrical abstraction conforms to the principle of grasping the world in a systematic way and making art comprehensible sensually as well as rationally. The geometrical abstraction tendencies in the HEUKING art collection can be summed up under the title “Forms of Color.” The most important representatives of this artistic current include Max Bill, Hans Richter, Günter Fruhtrunk and Imi Knoebel, as well as the most up-to-date contemporary tendencies.
