The most truly chaste, rich, and elegant carpets are those which are of one colour only, the pattern, if pattern it may be called, being formed by a judicious arrangement of every variety of shade of this colour. For instance, a Brussels carpet entirely red; the pattern formed by shades or tints varying from the deepest crimson (almost a black), to the palest pink (almost a white). Also one of green only, shaded from the darkest bottle-green, in some parts of the pattern, to the lightest pea-green in others. Or one in which there is no colour but brown, in all its various gradations, some of the shades being nearly black, others of a light buff.
