62. The wainscoting or dado should be the same as the top border or frieze, but of a darker tone. The intermixture of white or black is always permissible; thus a paper as a side-wall might have as its frieze the complementary coloring with more white, while the wainscoting or dado should be the complementary with black added.
63. The cornice should be lighter than the border, and its members may show several tints, with the ceiling lighter still.
64. As a rule the color of the chair coverings should be the complementary of the side-walls, and the color of the furniture frames should be complementary to the wainscoting; so by following this rule we find that the wainscoting serves as a contrasting background to the chair frame.
65. Let us imagine a room wherein the side-walls are of a reddish tint; the wainscoting, being a complementary color, is of a greenish cast. The furniture is of mahogany, and in contrast to the wainscoting, while the chair covering, being greenish in contrast to the chair frame, is also in contrast to the side-wall. Here we have, then, the color relations of side-wall, wainscoting, furniture-frames and covering; but it is undesirable that these tones should be in the same scale
