Victor Vasarely (1906-1997):
«Gestalt Rot», «Gestalt Grün», «Gestalt Blau», «Gestalt Gelb», 1971

The four murals by the French Op-Art artist, Victor Vasarely, were created in 1971 and specially designed for the former administration building of Zellweger Uster AG. They were initiated by the President of the Board of Directors, H.C. Bechtler. The works were placed in the spacious entrance hall, which takes up almost the entire length of the building. The four wall-filling panels (340 x 340cm) form a closed cycle. Each of the four panels contains 13 shades of colour. The arrangement of the geometric shapes as well as the sophisticated colour scheme create illusions of sculptural bodies that seem to dramatically emerge from the wall into the room.

From the 1940s onwards, Victor Vasarely worked mainly with geometric and abstract patterns such as squares, rhombuses, triangles, circles and rod shapes. The optical effect and kinetic phenomena were important to him. In the 1960s, Op-Art and other art movements such as Kinetics, but also Minimal Art, consciously involved the viewer in the perception of the artwork. Vasarely's desire to merge art and architecture into one was realised in the entrance hall of the administration building built by the architect Ronald Rohn.
