“Architecturally, color operates in conjunction with light and surface quality. Dark, warm colors plus low polish and low light create a more inviting environment than do bright, cold colors coupled with hard surfaces and high gloss. Color and light are traditionally used to set the stage, not only in the theater but wherever mood or the manipulation of space is important, because the size of an architectural area can be perceptually increased or decreased by varying color and light.”

—Joseph H. Krause, The Nature of Art, 1969.
