 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 transition between traditional European art and the new American art.
