According to the classification to pigment containing compounds, inorganic pigments can be subdivided into oxide, chromate, sulfate, silicate, borate, phosphate, molybdate, vanadate and iron thiocyanate, sulfide, metal hydroxide, etc.; organic pigments can be divided according to the chemical structure of compounds azo pigment, phthalocyanine pigment, anthraquinone, indigo family, quinacridone, two oxazine pigments, methane and other polycyclic aromatic pigments etc..

From the production perspective classification can be divided into titanium pigment, iron oxide pigments, chromium pigment, lead zinc pigments, pigments, metallic pigments, synthetic organic pigments, has the practical significance of the classification method, often a system can represent a major pigment production industry.
