Light Grey.
—Mix together one part of ultramarine blue, one part of lamp black, ten parts of white lead. By adding more or less white lead a darker or a lighter shade may be obtained if required. Another shade is obtained by mixing seven parts of black, four and one-eighth parts of white, and eight parts of blue.
Mastic.
—This is a dark gray shade. To produce it mix twelve parts of black with one of white, rather less than one of yellow and just a touch of orange.
Moss Gray.
—Tint white lead with French ochre, a bright green and a little lamp black.
Mouse Colour.
—Eleven parts burnt umber, to which has been added one part of Prussian blue, mixed with about twenty times the bulk of white lead, will give this tint. Another shade may be had by mixing sixteen parts of white, three of black and one of blue. Some painters tint white with lamp black and add a very little Venetian red and burnt umber.
Neutral Tint.
—An artist’s colour is sold under this name.
