— Sulfides: zinc sulfide, cadmium sulfide

— Chromates: chrome yellow, chrome orange, zinc chromate

— Molybdates: molybdate orange, zinc molybdate

— Phosphates: zinc phosphates, aluminum phosphate

— Elements

— Metallic: aluminum, copper, zinc

— Non-metallic: carbon black

— Coordination complex: iron blue

— Others: ultramarine blue, bismuth vanadate, zinc metaborate

• Organic pigments

— Azo pigments

— Monoazo pigments: toluidine red, arylamide yellow, naph — thol red
