Inorganic pigments derive from mineral origins and are considered metal compounds. These pigments are siennas, umbers, and ochres that form within clays in the Earth. They can be synthetically created to produce signature colors such as "cobalt blue" and "titanium white."
Organic pigments vs. Inorganic pigments
Whether pigments are sold naturally or synthetically will alter results in consumer products. Natural pigments are generally less expensive and originate from silica, mica, calcium carbonate, zinc oxide, and clays. Synthetic pigments include synthetic molecules such as calcined clay, pyrogenic silica, and blanc fixe for tougher products.
No matter which pigments you use for paint, remember that pigment volume concentrate (PVC) alters appearance. A low PVC results in a gloss finish, and a high PVC provides a flat look when dry.
