as decorative elements the contrast of dark and light areas gives definition to the object. if a vertical wall is lit at an angle of about 45 degrees above the wall (for example, by the sun) then adding a small overhanging horizontal molding, called a fillet molding, will introduce a dark horizontal shadow below it. adding a vertical fillet to a horizontal surface will create a light vertical shadow. graded shadows are possible by using moldings in different shapes: the concave "cavetto" molding produces a horizontal shadow that is darker at the top and lighter at the bottom; an "ovolo" (convex) molding makes a shadow that is lighter at the top and darker at the bottom. other varieties of concave molding are the "scotia" and "congé" and other convex moldings the "echinus", the "torus" and the astragal.
