gray, there being no color present. Six parts of white lead, two parts of Venetian red, and one part of lamp black gives a somewhat dark pearl gray, but a lighter tint may easily be obtained by adding more lead. Ivory black answers equally as well as lamp black.
Quaker Drab. This greenish gray shade is produced by mixing two parts each of yellow and green and five parts of white.
Rustic Drab. Tint white lead with French ochre and lamp black.
Silver Gray. Tint white lead with French ochre and lamp black, or yellow may be employed instead of the ochre if preferred. White lead tinted with a little lamp black and indigo gives an excellent silver gray.
Smoke Gray. Tint white lead with French ochre and lamp black.
Steel Gray. Tint white lead with a mixture of lemon chrome and medium chrome and lamp black.
Stone Gray. Add black and chrome to white lead.
Verdant Gray. Two parts of oxide zinc and one part of terra verte.

Aloes. A pale sage green shade. To obtain it mix six parts of black, three of white, one of chrome yellow, and three of Brunswick green.
Apple Green. The simplest way to obtain this is to mix medium chrome green with about thirty times the quantity of white lead, but other greens may be employed with the addition of a little Prussian blue when necessary. Or a little orange chrome yellow may be added to the medium chrome
