4. White or whitish hangings of a light grey (either normal green, blue, or yellow), uniform or with velvet patterns of the colour of the ground, are also very useful. 5. When we would choose hangings upon which to place a picture, their colour must be uniform, and make the greatest contrast possible with that which predominates in the picture, if the hangings are not of a normal grey. I shall return to this assortment (483). 464. Hangings in the best taste are those— 1. Which present designs of a light tone, either normal or coloured grey, upon a white ground, or the reverse, and in which the pattern is at least equal in extent of surface to the ground; for a small pattern has a very poor effect, at least in a large room. 2. Patterns of two or more tones of the same or very near scales assorted conformably to the law of contrast. 465. Hangings of brilliant and varied colours representing real objects, forming patterns more or less complex, do not admit of pictures; and as such hangings should exhibit themselves distinctly, they must not be concealed by the furniture in any of their parts. 466. When we have to adapt a border to a monochromous hanging, or to one presenting a dominant colour, we must first determine whether we can have recourse to a harmony of analogy or to a harmony of contrast; in all cases the border ought to detach itself more or less from the hangings, which it is intended to surround and separate from contiguous objects. Harmony of contrast is the most suitable to papers of a uniform pure colour, such as yellows, greens, and blues; consequently we recommend for the dominant colour of the border, the complementary of that of the hangings, whether this border represents ornaments, arabesques, flowers, or imitations of fringes or tissues. But, as a contrast of colour ought not generally to offer also a contrast of tone, then the general tone of the border must only surpass that of the hangings so far as to avoid a deadening effect. If a double border be required, the exterior border must be of a much deeper tone than the other, and always narrower. 467. Among the colours suitable for borders we recommend the following as harmonies of contrast:— 1. For yellow hangings, violet and blue mixed with white; if a fringe, of flowers garnished with their leaves, or ornaments. 2. For green hangings, red in all its hues; the painted gilt-yellows upon a dark-red ground; the borders of brass. 3. For white hangings, orange and yellow; the borders of brass or gilt moulding: these are much better on blue than on green. 468. Among the harmonies of analogy, I recommend the following:— For yellow hangings, a border of brass or gilt moulding.
