"Hair is a troublesome thing to get right. For golden hair I use a very thin wash of burnt sienna; for the half tones a purple tint—blue and red mixed in equal parts, and for the deep shadows burnt sienna. For ordinary dark hair nothing is better than sepia, and for the high lights a purple grey—blue and a touch of red—that gives a glossiness to the hair. For grey hair simply mix sepia and ultramarine; for red hair burnt sienna is used principally, shaded with sepia in the dark parts.
"Backgrounds—for the ordinary, deep, plain, brownish, the best thing is a wash of burnt sienna and ultramarine, in proportions as required to obtain warmer or cooler effects. For a cloudy sky or background use cobalt for the blue and light red mixed with cobalt for the deeper shadows; where the shadows come near the figure, use brown madder and cobalt; touch the edges of the clouds with light red alone, to give a warm, cloudy effect.
"Draperies—for a man's black coat use blue-black and cobalt, mixed in about equal proportions, and a little madder lake; put in the shadows with sepia. For a lady's black silk use much the same, only less blue-black and more cobalt, with a little light red in it; use sepia again for the shadows, as it gives a warmer tone than black itself. If lights are required on a black coat when it is too black, body colour must be used—white, with a little light red mixed with it."
