    Abstract: An inorganic red pigment is provided which pigment comprises titanium oxide, tin oxide, zinc oxide, and tungsten oxide, wherein the molar ratios of the oxides correspond to a composition of formula (TiO2)a(SnOx)b(ZnO)c(WO3)d  (I), wherein SnOx comprises SnO and SnO2 in a molar ratio of SnO:SnO2 of from 70:30 to 100:0; 0.8≦̸a≦̸3.0; 0.3≦̸b≦̸2.0; 0.3≦̸c≦̸1.3; and 0.01≦̸d≦̸0.8. Optionally, SiO2, other metal oxides or metal sulfides may be present. The inorganic pigment may be used as colorant in various applications.
