Nevertheless it does not prevent its participating more of the colour of a small object near it, than of a large one more remote. See the sixth proposition of perspective, which says, that large objects may be situated at such a distance as to appear less than small ones that are near.   draperies will make the flesh of the human figure appear whiter than in reality it is ; and white draperies, on the contrary, will make it appear darker. Yellow will render it higher coloured, while red will make it pale.   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.
