Old Gold.
—Use middle chrome with a little vermilion and burnt sienna, and add a very little cobalt. A cheaper colour may be made by mixing ochre and burnt sienna. One part of green and three of bright yellow mixed with a little white will give an old gold shade. Or it may be obtained in the same way as [Gold], which see, but a little burnt umber may be added. Some painters prefer to tint white lead with a mixture of chrome, raw sienna and vermilion.
Olive Yellow.
—This colour is sometimes called olive brown. It is made by mixing three parts of burnt umber with one part of lemon chrome yellow, a larger quantity of yellow being added if a lighter shade is required. Another method is to mix ten parts of black, one of orange, twelve of yellow, and five of green.
Orange.
—Mix white, yellow and orange in the following proportions: one part each of yellow and white and eighteen parts of orange. Or another shade is got with seventeen parts of orange, six of yellow and two of white. Orange chrome yellow can be easily purchased, however, and gives this colour without any admixture being necessary.
Persian Orange.
—Mix fourteen parts of orange chrome, five parts of yellow ochre and one of white.
Pompeian Yellow.
—Tint white with Italian ochre and add a very little ultramarine and vermilion.
