Distant greens are generally gray and cool in quality

The tones of the middle distance occupy a place between.

A few leaves in the foreground may be drawn in detail. The trunks of trees should be treated in the same way, and the small branches drawn in with a fine pointed brush where they are most prominently seen, and merely suggested in other parts.

A few combinations of color that may prove useful to the beginner are here given.

For blue skies use: Cobalt, silver white, a little light cadmium, a little madder lake and enough ivory black to give quality. Clouds are painted with silver white, yellow ochre, ivory black, light red and cobalt, adding madder lake in the cooler tones, and burnt sienna in the deep shadows.
