The hangings or the pictures must present only normal grey, or a grey of a colour more or less broken; the chairs must be black or of a dark grey, either normal or coloured; and in this case we can take a grey tinted with the complementary of the colour of the grey of the hangings. If more contrast is desired, we can have recourse to the brown tones of this complementary of the colour, which tints the grey of the hangings. 478. _Window and Bed-curtains_ should be similar to each other. _When the Chairs have a decided Colour—such as Red, Yellow, Green, Blue, or Violet_—the hangings should be of a pure colour, contrasting favourably with that of the chairs. The curtains should generally be of the colour of the chairs, and their borders of the colour of the hangings, or of the colour of the hangings bordered with the colour of the chairs. _The Chairs being Grey, or of a very subdued Colour_, and the hangings of a decided colour, the curtains should be either,—1. Of the colour of the chairs, with a border of the colour of the hangings: or, 2. Of the complementary of the hangings, or contrasting favourably with them; the colour of the border should be that of the hangings. _The Hangings being of a Grey Colour, or White_, the curtains should be,—1. Of the colour of the chairs: or, 2. Of a pure colour, complementary to the grey of the hangings, if the latter do not belong to the scale of normal grey. 479. _Doors._—Doors being, by their use, size, and position, relatively to the plane of the wall, absolutely distinct from the wainscoting, should be distinguished from it by their colour, notwithstanding the contrary practice of painters, who make them the same. Their different parts might be painted in many low tones of the same, or of approximating scales, and always according to the harmony of analogy, as the parts of one object are concerned. The colour of the doors should be of normal grey, or of a grey tinged with the colour of the hangings or of its complementary, which will thus always unite with the hangings, either by harmony of analogy, or by harmony of contrast. The door frames should be darker than the door itself. 480. _Window Frames_ should be like the doors, according to a rule which has long been generally observed. The fastenings must be black, bronzed, or of brass. _Carpets._ 481. Whatever may be the dominant colours of the subjects represented in their central part, with regard to brilliancy and contrast, they should always be separated from the chairs by a sufficient interval to prevent discord with the colour of the latter. 1. The more numerous and vivid the colours are, the more we must control their brilliancy; and the carpet most suitable will be one of simple colours and pattern. In many cases, an assortment of green and black will have a good effect.
