Until now, it has been possible to color white titanium oxide by doping with transition metal ions, but it is difficult to avoid biotoxicity derived from transition metals. Features and Uniqueness In the present invention, titanium oxide inorganic pigments that do not contain transition metals and have various colors such as white, yellow, red, gray, green, purple, black, and skin color have been realized. Practical Application New applications of titanium oxide pigments are expected in the cosmetics field, where biotoxicity is an issue.
