Rh : two parts of burnt sienna, three parts of light ultramarine blue, sixty party of zinc white.

Black Slate. Mix together black and Prussian blue in the proportion of about thirteen parts of the former to one of the latter and add a little white.

Dark Gray. Mix eight parts of black, one of white and a touch of red or blue to produce this shade; but practically any admixture of black and white in which the former predominates and to which has been added a little color will give a dark gray.

Dark Lead. This is a dark gray, being produced simply by adding lamp black to white lead.

Dark Slate. This also is black added to white. The mixture under Black Slate would answer.

Deep Lead. Black, a little bright blue, and Indian red mixed with white lead produces this color.

French Gray. This can be made by tinting white with a little ivory or drop black and adding a little carmine or crimson lake and ultramarine. This produces a very slight violet tinge. White tinted with a little ultramarine and Venetian red also gives a good French gray. Celestial blue or cobalt may be used instead of the ultramarine if desired. Another good mixture is made by tinting white lead with one part of black and two parts of orange chrome.

Granite. French ochre and lamp black added to white lead produce this color.

Graystone.–Mix five parts of black with three of white and three of blue and add a little red.

Gray Drab. Mix five parts of black with four of white and a little deep chrome yellow.

Green Slate. Same as lead, but with more black and blue.

Iron Gray. Mix eight parts of black with two of white and a little orange.

Jasper. This may be described as a pepper and salt shade.
