Usage: Paint, Stain, Dye. These denote three different processes; the first mechanical, the other two, chiefly chemical. To paint a thing is to spread a coat of coloring matter over it; to stain or dye a thing is to impart color to its substance. To stain is said chiefly of solids, as wood, glass, paper; to dye, of fibrous substances, textile fabrics, etc.; the one, commonly, a simple process, as applying a wash; the other more complex, as fixing colors by mordants. [1913 Webster]
