Rh Straw Color. Lemon chrome mixed with raw umber.

Straw. White lead tinted with a little chrome yellow produces an excellent straw tint, but some prefer to add a little French ochre. Or medium chrome yellow may be used as a base, and a mixture added of white, French ochre and Venetian red.

Yellow Lake. This is a somewhat fugitive color which has but little body, but is useful for glazing. To imitate it use equal parts of burnt umber and white lead and tint with chrome yellow and lake. Or, mix umber and white in equal proportions and add Naples yellow and scarlet lake. To obtain this color in its full richness it is quite necessary to glaze either admixture with yellow lake.

Yellow Ochre. The ochres are natural mineral pigments, which are among the cheapest and most useful at the command of house painters. They can be used in any vehicle and are quite permanent, while they do not affect any other color with which they may be used.

Zinc Yellow. This is a chromate of zinc which is quite fast in light, and possesses the advantage of permanence even in the presence of impure sulphuretted hydrogen. It may be mixed with other colors, without adversely affecting them.
