Note 39 — THE BRITISH VILLA.—PRINCIPLES OF COMPOSITION.

The epithet "raw," by the by, is vague, and needs definition. Every tint is raw which is perfectly opaque, and has not all the three primitive colors in its composition. Thus, black is always raw, because it has no color; white never, because it has all colors. No tint can be raw which is not opaque; and opacity may be taken away, either by actual depth and transparency, as in the sky; by luster and texture, as in the case of silk and velvet, or by variety of shade as in forest verdure. Two instances will be sufficient to prove the truth of this. Brick, when first fired, is always raw; but when it has been a little weathered, it acquires a slight blue tint, assisted by the gray of the mortar: incipient vegetation affords it the yellow. It thus obtains an admixture of the three colors, and is raw no longer. An old woman's red cloak, though glaring, is never raw; for it must of necessity have folded shades: those shades are of a rich gray; no gray can exist without yellow and blue. We have then three colors, and no rawness. It must be observed however, that when any one of the colors is given in so slight a degree that it can be overpowered by certain effects of light, the united color, when opaque, will be raw. Thus many flesh-colors are raw; because, though they must have a little blue in their composition, it is too little to be efficiently visible in a strong light.
