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. |
