Modeling Information
Pigments are colored particles that add color to other materials by absorbing or scattering light.
They are often powdery and are mixed with a liquid to add color to materials like paints, inks, plastics, and rubber. Pigments are chemically unreactive and nearly or completely insoluble in water or other mediums. They require a binder to dissolve into liquids.
