Place two sheets of paper of either of the above colours beside two sheets of flesh-coloured paper, when it will be seen how much they are mutually injured, the lighter becoming greenish, and the darker rather of a violet hue. By substituting light green for the red, we shall find them mutually heightened and improved. The height of tone of the green influences the result: a very deep green, acting by contrast of tone, so enfeebles the complexion, that the slight contrasts of its colours will be inappreciable; a deep red, by contrast of analogy, blanches the complexion. It is necessary, then, to separate the rose from the skin, in some manner; and the simplest manner of doing this, is to edge the draperies with a border of _tulle_, which produces the effect of grey by the mixture of white threads, which reflect light, and the interstices, which absorb it; there is also a mixture of light and shade, which recalls the effect of grey, like the effect of a casement-window viewed at a great distance. Dark red is less objectionable for certain complexions than rose-red, because, being higher than the latter, it tends to impart whiteness to them in consequence of contrast of tone. 504. DELICATE GREEN is, on the contrary, favourable to all fair complexions which are deficient in rose, and which may have more imparted to them without disadvantage. But it is not as favourable to complexions that are more red than rosy; nor to those that have a tint of orange mixed with brown, because the red they add to this tint will be of a brick-red hue. In the latter case a dark green will be less objectionable than a delicate green. 505. YELLOW imparts violet to a fair skin, and in this view it is less favourable than the delicate green. To those skins which are more yellow than orange it imparts white; but this combination is very dull and heavy for a fair complexion. When the skin is tinted more with orange than yellow, we can make it rosy by neutralizing the yellow. It produces this effect upon the black-haired type, and it is thus _that it suits brunettes_. 506. VIOLET, the complementary of yellow, produces contrary effects; thus it imparts some greenish-yellow to fair complexions. It augments the yellow tint of yellow and orange skins. The little blue there may be in a complexion it makes green-violet. This, then, is one of the least favourable colours to the skin, at least when it is not sufficiently deep to whiten the skin by contrast of tone. 507. BLUE imparts orange, which combines favourably with white, and the light flesh tints of fair complexions, which have already a more or less determined tint of this colour. Blue is thus suitable to most blondes, and in this case justifies its reputation. It will not suit brunettes, since they have already too much of orange. 508. ORANGE is too brilliant to be elegant; it makes fair complexions blue, whitens those which have an orange tint, and gives a green hue to those of a yellow tint.
