We delight in the mere sight of the delicate glow of fading rays clinging to the surface of a dusky wall, there to live out what little life remains to them. We never tire of the sight, for to us this pale glow and these dim shadows far surpass any ornament. And so, as we must if we are not to disturb the glow, we finish the walls in 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.
