Plum.
—Mix with equal parts of white lead, Indian red and ultramarine blue in the proportion of two parts of lead to one of each of other colours. This makes a dark plum that is only suitable for inside work. If a light tint is desired add more white lead. A very rich plum may be obtained by mixing together ultramarine blue and carmine, and adding a little white and a little yellow.
Pompeian Red.
—Small quantities of red and orange are mixed with black to produce this shade.
Poppy.
Blue and vermilion mixed in the proportion of one of the former to twenty-four of the latter give this shade.
Purple.
—Light Indian red, four parts; white lead, three parts; ultramarine blue, two parts; or a purple may be obtained by mixing Indian red and white. A mixture preferred by some painters is made by mixing ultramarine and vermilion with a little white. A little crimson lake gives richness to the colour.
Red Ochre.
—This earth colour is cheap, and can be readily bought in most places. It can be imitated by mixing India red and chrome and adding a little vermilion.
