The works by German painter Herbert Hamak do not fit into one of the traditional categories of art, like painting or sculpture, but are covered by both at the same time. Hamak’s work concentrates on the purity of color​ as it is intensified by the intentional use of resin-filtered light that is the essence of his body of work. His work has been shown in numerous international museums and collections like the Museo Lapidario Maffeiano, Verona, the Museum Haus Lange in Krefeld, the Peggy Guggenheim Collection, Venice, the Kunsthalle Mannheim, the Württembergische Kunstverein, Stuttgart, the Museum für Moderne Kunst, Frankfurt am Main, the Stiftung für konstruktive und konkrete Kunst, Daimler-Chrysler Collection, Zürich, the Musée d'Art Moderne et Contemporain, Genève and many others.
