PURPOSE: A color polyimide composition is provided to provide a color polyimide film with improved heat resistance, insulating, chemical resistance, and alkali resistance, and flexibility. CONSTITUTION: A color polyimide composition consists of a polyimide, color pigment, or carbon nanotube black pigment, dispersant, and leveling agent. A manufacturing method of the color polyimide composition comprises; a step of first polymerization by injecting a diamine monomer into a reaction solvent; a step of second polymerization by injecting acid anhydride into a separate reaction solvent; a step of forming a polyamic acid by mixing the products of the polymerizations, and injecting pigment, dispersant, and leveling agent; and a step of curing the polyamic acid.
