A Treatise on Painting/Chapter 252
Chap. CCLII.—Of the Shadows of White.
To any white body receiving the light from the sun, or the air, the shadows should be of a blueish cast; because white is no colour, but a receiver of all colours; and as by the fourth proposition[1] we learn, that the surface of any object participates of the colours of other objects near it, it is evident that a white surface will participate of the colour of the air by which it is surrounded.
