Chap. CCLXXXII.—Where the Reflexes are seen.
Of all reflexions of the same shape, size, and strength, that will be more or less strong, which terminates on a ground more or less dark.
The surface of those bodies will partake most of the colour of the object that reflects it, which receive that reflexion by the most nearly equal angles.
Of the colours of objects reflected upon any opposite surface by equal angles, that will be the most distinct which has its reflecting ray the shortest.
Of all colours, reflected under equal angles, and at equal distance upon the opposite body, those will be the strongest, which come reflected by the lightest coloured body.
That object will reflect its own colour most precisely on the opposite object, which has not round it any colour that clashes with its own; and consequently that reflected colour will be most confused which takes its origin from a variety of bodies of different colours.
That colour which is nearest the opposed object, will tinge it the most strongly; and vice versâ: let the painter, therefore, in his reflexes on the human body, particularly on the flesh colour, mix some of the colour of the drapery which comes nearest to it; but not pronounce it too distinctly, if there be not good reason for it.
