The Analine Colors are obtained from coal tar or nitro benzole. If nitro benzole is treated with iron filings and acetic acid in the proper apparatus, aniline is produced. Various aniline colors are made from this product by treatment with chemicals. The processes are too complicated to be entered into and of little practical interest to the paint trade.

The various aniline colors have replaced the vegetable lakes in large part, and find extended use as stains; in improving the color and tone of cheaper pigments; and in the production of artificial vermillions before mentioned. Aniline colors find their chief use, however, as dye stuffs for all possible purposes where dyes are required.
