And so, as we must if we are not to disturb the glow, we finish the walls with sand in a single neutral color. The hue may differ from room to room, but the degree of difference will be ever so slight; not so much a difference in color as in shade, a difference that will seem to exist only in the mood of the viewer. And from these delicate differences in the hue of the walls, the shadows in each room take on a tinge peculiarly their own.

Of course the Japanese room does have its picture alcove, and in it a hanging scroll and a flower arrangement. But the scroll and the flowers serve not as ornament but rather to give depth to the shadows. We value a scroll above all for the way it blends with the walls of the alcove, and thus we consider the mounting quite as important as the calligraphy or painting. Even the greatest masterpiece will lose its worth as a scroll if it fails to blend with the alcove, while a work of no particular distinction may blend beautifully with the room and set off to unexpected advantage both itself and its surroundings.

Wherein lies the power of an otherwise ordinary work to produce such an effect?
