CHAPTER III.
SECTION IV.
SUNSET.
At Sunset there is even less variety of colour observable in the illumined parts of objects than when the sun is higher in the sky.
This arises from the influence of the atmosphere previously alluded to. A greater quantity of the medium is loaded with light, and the local colours of the objects seen through it are consequently affected to a greater degree thereby. The colour of the light is also affected by the medium through which it passes, and it becomes much richer, and more nearly approaching to orange.
The light in the sky, or illuminating power, is made yellow; but the lights on objects are rendered of a fleshy colour, which is made to appear warmer by the opposition of positive purple shadows, while those objects which do not receive any of the sun's light are kept very cool grey (the effect of reflected light from the blue sky), which by contrast throws the whole of the illuminated part of the picture into warmth.

SECTION V.
MOONLIGHT.
The light of the moon being white or silvery grey, the shadows are made comparatively warm browns. The appearance of moonlight is given by the colours on the illuminated objects in the picture, which are made to appear cooler than they really are, by the contrast with the warm shadows. By this means, much more colour may be introduced into the light than is usually observed in Nature, and without impairing the effect of moonlight; and the Bianchi contend that by such means greater brilliancy is obtained. The blues in the sky near the moon are kept very pure for the same purpose. Plate.

CHAPTER III.
SECTION VI.
GREY DAYLIGHT.
Grey daylight also affords brownish shadows, but from the greater quantity and diffusion of comparatively colourless light, the local colours of objects become more visible, while the shadows are more varied by reflection and refraction. Reflections take their colours from those of the objects by which they are occasioned. The lights on objects are treated as in the case of moonlight; they are made _positively_ warmer than they appear in nature, and are rendered _comparatively_ cool by the warmth of the shadows.--Plate.
The degrees to which these licences may be carried, must depend upon the style of colouring adopted. The Amateur has had them placed before him, and whichever he may choose, he will be certain to meet with success in the eyes of one party; he cannot hope to please all.
