The Städtische Galerie im Lenbachhaus and the Kunstmuseum Bonn have teamed up to present the exhibition "Mentally Yellow. High Noon", a double presentation of art from the KiCo Collection. Assembled by Doris Keller-Riemer and Hans-Gerd Riemer, Bonn, the KiCo Collection has been hosted by the two museums in Bonn and Munich since the mid-1990s. Initially focused on monochrome color painting, it has steadily grown over the course of two decades to encompass a wide spectrum of contemporary art, including several expansive installations. In purchasing new art, the Riemers have sought to buy complete ensembles or entire self-contained rooms. The works are given on permanent loan to the public museums, and decisions concerning acquisitions are made in close collaboration and coordination between the collectors and the two museums. The KiCo Collection thus also complements the museums’ own holdings in helpful and interesting ways. Its contributions have allowed the Lenbachhaus as well as the Kunstmuseum Bonn pursue their own distinctive collection-building programs, a form of support that will remain vital in years to come.
