Complex inorganic coloured pigments (CICPs) are typically crystals of mixed metal oxides that are produced by a high temperature calcination process. CIPs have a defined crystal structure (e.g. rutile and spinel). The variable combination of metals and structures provide the desired colour to the pigment.

Further support can be found through Eurocolour and the Inorganic pigments consortium.

Eurocolour has published guidance for the identification of CICPs. Please follow this guidance when you are identifying CICPs.
