A method for filling multiple colors of liquid color cosmetic materials, comprises the steps of: separating a sponge, into a plurality of sponge pieces by dividing the sponge; forming a coating film on the outer lateral side, or on the outer lateral side and on the lower surface of each of a plurality of the sponge pieces; impregnating different liquid color cosmetic materials into each of the sponge pieces having a coating film formed thereon; and fitting the angles of each of the sponge pieces, and coupling the sponge pieces. Liquid cosmetic materials having different colors are not mixed in one container without comprising a separate partition film, and a boundary line is clearly distinguished.
