A powdered substance used for coloring. It is insoluble in water, grease, resin, organic solvent and other media, but can be evenly dispersed in these media and can make the media colored, and has a certain covering power. The basic requirements of pigments used in art are that the finer the particles are, the brighter the color is, and the longer the color is, the better the stability is. Watercolor pigments are almost transparent except white. This can meet the needs of watercolor cover dyeing.
