On the Sublime and Beautiful/Part III/Chapter 17
AS to the colours usually found in beautiful bodies, it may be somewhat difficult to ascertain them, because, in the several parts of nature, there is an infinite variety. However, even in this variety, we may mark out something on which to settle. First, the colours of beautiful bodies must not be dusky or muddy, but clean and fair. Secondly, they must not be of the strongest kind. Those which seem most appropriated to beauty, are the milder of every sort; light greens; soft blues; weak whites; pink reds; and violets. Thirdly, if the colours be strong and vivid, they are always diversified, and the object is never of one strong colour; there are almost always such a number of them, (as in variegated flowers,) that the strength and glare of each is considerably abated. In a fine complexion, there is not only some variety in the colouring, but the colours: neither the red nor the white are strong and glaring. Besides, they are mixed in such a manner, and with such gradations, that it is impossible to fix the bounds. On the same principle it is, that the dubious colour in the necks and tails of peacocks, and about the heads of drakes, is so very agreeable. In reality, the beauty both of shape and colouring are as nearly related, as we can well suppose it possible for things of such different natures to be.
