Zusammenfassung:	PURPOSE: A colored ceramic composition and a method for manufacturing the same are provided to minimize the volatilization of a pigment by using impurity-containing alumina and implementing a sintering process at a temperature lower than or equal to 1500 degrees Celsius. CONSTITUTION: A colored ceramic composition includes 2 to 20 parts by weight of a pigment based on 100 parts by weight of a ceramic mixture. The ceramic mixture includes 60-85 weight% of alumina, 5-30 weight% of stabilizing zirconia, and 5-15 weight% of oxides. A method for manufacturing the colored ceramic composition includes the following: The ceramic mixture is prepared. The pigment is mixed with the ceramic mixture to form the colored ceramic composition. The colored ceramic composition is sintered at a temperature between 1250 and 1500 degrees Celsius.
