78 parts of zinc white. Another shade may be obtained by mixing forty-four parts of white, twenty-nine of green and twenty-seven of blue. Or celestial blue and a little red on a base of white will give an azure shade.

Blue Grass Tint. One part of Prussian blue, three parts of emerald green, seven parts of white lead.
