1. By a white drapery which heightens by contrast of tone. 2. By a drapery the colour of which is exactly the complementary of the tint, and of which the tone is not too high; such as perhaps a green drapery for a rosy complexion; or perhaps a blue drapery for the orange complexion of a blonde. The tint may be heightened by making it leave its scale:— 1. By a green drapery of a light tone upon an orange complexion. 2. By a blue drapery of a light tone upon a rosy complexion. 3. By a yellow, canary, or straw-coloured drapery, upon an orange complexion, of which the complementary violet neutralizes some of the yellow of the complexion, and heightens its rose. 546. _Note._—The modifications resulting from the juxtaposition of parts diversely coloured are much more positive than those arising from reflection by one part upon another. _If the Painter wishes to dissimulate a Tint of the Complexion—_ 547. As above, he must distinguish two cases:— 1st, WHEN HE SEES THE COLOURS MODIFIED BY JUXTAPOSITION ONLY, _when the tint may be lowered without leaving its scale_:— 1. By a black drapery, which lowers it by contrast of tone. 2. By a drapery of the same scale as that of the tint, but of a much higher tone. Such, perhaps, as a red drapery upon a rosy complexion; or, an orange drapery upon an orange-tinted complexion; or, the effect of a dark green drapery on a complexion of a green tint. 2nd, _The tint may be lowered by making it leave its scale_. 1. By a green drapery of very dark tone, upon an orange complexion. 2. By a blue drapery of a dark tone, upon a rosy complexion. 3. By a very dark yellow drapery, upon a very pale orange complexion. APPLICATIONS TO HORTICULTURE. SECTION I. 548. The applications I propose to make are of two kinds: the one relating particularly to the arrangement of plants in gardens, according to the colour of the flowers; the other, to the method of distributing and planting ligneous plants in masses, which I suppose to have been previously planned. Doubtless, I need not have discussed the latter subject, but I have been led to it so naturally, and the rules which guided me are so positive and simple, that I have no doubt of their proving profitable to those of my readers who follow them in laying out plantations, &c. The artist who conducts these operations is called a Gardener, or Landscape Gardener.
