New inorganic red pigments based on Cr-doped $Y_2O_3$ and $Al_2O_3$ were synthesized by solid state method and characterization of their pigments were characterized by using XRD, FT-IR, SEM and UV-Vis spectrophotometer. The single perovskite phase revealed at $1450^{circ}C{sim}1550^{circ}C$ for 6 h due to using mineralizers. The color of pigment powders resulted out various red-shades depending on the compositions of used materials and temperatures. Glazed tiles painted with pigment powders showed red color in oxidation and reduction firing. The best red colour was obtained when the $Cr_2O_3$ was used 0.04 mole at $1450^{circ}C$ for 6 h.
