Pigments are used for coloring paint, ink, plastic, fabric, cosmetics, food and other materials. Most pigments used in manufacturing and the visual arts are dry colorants, usually ground into a fine powder. A pigment must have a high tinting strength relative to the materials it colors. It must be stable in solid form at ambient temperatures
