Arrange the paper for the painting, after sponging it, by stretching upon a drawing board, and then turn to the mixing of the colors.

Colors Used for Skies and Distances.

For blue of sky.—Cobalt Blue, lowered with Pink Madder and Gamboge, to the hue required. Ochre may be substituted for Gamboge.

Clouds.—The same mixed so as to form a variety of warm and cool pearly greys.

For Extreme Distance.—Cobalt and Venetian Red.

For Local Tints.—Blend the colors so that the tints produced may incline toward yellow, red, or any tint required.

For Middle Tints, use Indigo, Pink Madder and Ochre on the same principle for the light parts, and Indigo, Pink Madder and Gamboge for shady portions.

Setting Sun.—Use Yellow Ochre and Pink Madder, or Venetian Red and Yellow Ochre; sometimes Vermilion and Gamboge or Indian Yellow in small proportions, when a strong effect is to be given.

Trees.—In painting trees use Indigo, Burnt Sienna and Gamboge. These colors will make tints for the light; Indigo mixed with Vandyke Brown becomes a fine deep grey, of a green hue. Purple Lake may be added when you want the tint more neutral.
