"An idea that comes from the widely accepted view that the colors of nature are, in the main, beautiful, harmonious, and satisfying is that the use of only the natural colors of materials will guarantee successful color in architecture and interior design...
...This is an idea that can be traced back to the Arts and Crafts movement of the nineteenth century with its abhorrence of the use of harsh and ill-considered artificial coloring and its respect for the integrity of natural materials unfinished or finished so as to display their natural coloring."
