white and brown that recede into two bronze centers to create an illusion of depth. In the 1960s, Walter Gropius, who was designing the Pan Am Building with Emery Roth & Sons and Pietro Belluschi, commissioned Albers to make a mural. The artist reworked City, a sandblasted glass construction that he had designed in 1929 at the Bauhaus, and renamed it Manhattan. The giant abstract mural of black, white, and red strips arranged in interwoven columns stood 28-feet high and 55-feet wide and was installed in the lobby of the building; it was removed during a lobby redesign around 2000. Before he died in 1976, Albers left exact specifications of the work so that it could easily be replicated; in 2019, it was replicated and reinstalled in its original place in the Pan Am building, now renamed MetLife. In 1967, his painted mural Growth (1965) as well as Loggia Wall (1965), a brick relief, were installed on the campus of the Rochester Institute of Technology. Other architectural works include Gemini (1972), a stainless steel relief for the Grand Avenue National Bank lobby in Kansas City, Missouri, and Reclining Figure (1972), a mosaic mural for the Celanese Building in Manhattan destroyed in 1980. At the invitation of a former student, the Australian architect Harry Seidler, Albers designed the mural Wrestling (1976) for the Mutual Life Centre in Sydney. Color theory In 1963, Albers published Interaction of Color, which is a record of an experiential way of studying and teaching color. He asserted that color "is almost never seen as it really is" and that "color deceives continually", and he suggested that color is best studied via experience, underpinned by experimentation and observation. The very rare first edition has a limited printing of only 2,000 copies and contained 150 silk screen plates. This work has since been republished, and is now available as an iPad App. Albers presented color systems at the end of his courses (and at the end of 'Interaction of Color') and these featured descriptions of primary, secondary and tertiary color, as well as a range of connotations that he assigned to specific colors on his triangular color model. In respect to his artworks, Albers was known to meticulously list the specific manufacturer's colours and varnishes he used on the back of his works, as if the colours were catalogued components of an optical experiment. His work represents a
