PURPOSE: Color aluminum and a manufacturing method thereof are provided to maintain the same color from the surface to the inside of the color aluminum by producing aluminum raw material with extruded pellet extruded from an extruder which mixes aluminum raw materials and pigments. CONSTITUTION: A manufacturing method of color aluminum having the same color from surface to inside comprises the following steps: An aluminum material and a pigment are fused into a molten metal, extruded by an extruder, and cut into a uniform particle shape. A catalyst for lowering a melting point is added to the aluminum raw material and the pigment.
