by Arthur Seymour Jennings

Prussian Blue.

—This colour is certainly the most important blue the house painter has. It cannot be imitated. It works well in both water and oil, and is transparent.

Quaker Blue.

—Add a little black to Prussian blue, and lighten up with white.

Robin’s Egg Blue.

—Use white for base, tint with ultramarine until a fairly strong blue is obtained, and then tinge with a little lemon chrome green.

Royal Blue.

—This is made by adding a little white to Prussian blue with a touch of crimson lake. Some manufacturers make a very rich blue, which they sell under the name of Royal blue.

Sapphire Blue.

—One part of Chinese blue mixed with double the quantity of oxide of zinc. This should not be used for outside work.
