Inorganic pigment is excellent at stability to human body and compatibility with different materials and has been used in a variety of field such as cosmetics, printing inks, paints, and construction materials for improving the aesthetic features. In this paper, hydrothermal synthesis method was used to prepare the manganese and iron dopped with titania pigment. As process parameters, the amount of manganese precursor and iron precursor, and calcined temperature was changed. Optimum amounts of manganese and iron dopped with titania precursor to give excellent color index was manganese 1.0wt% and iron 1.5wt% for dopped titania, and Optimum calcination temperature was $550^{\circ}C$. The synthesized pigments were analyzed by XRD, SEM, EDS, Spectrophotometer and UV-Vis Spectrometer.
