[Fr., from L. pingere, to paint.] All paints are made up of the substance which gives the color, usually called the pigment, and that with which the color is mixed. Pigments are mostly made from minerals, but some are got from vegetables and some from animals. Paints are mixed either with oil or water, and are therefore called oil-paints or water-colors. Oil-paints are usually mixed with linseed oil, but sometimes some kinds of nut oils are used. Water colors are mixed with water and a little glue or gum.
