The water-borne metallic color coating composition can provide a coating film having the above-superior properties and an excellent flip-flop property, by a two-coating and one-baking application method, without disturbing the orientation of the luster color pigment(s) therein before/after an application of a clear coating composition and without adversely effecting on the flip-flop property. The present invention provides a water-borne metallic color coating composition comprising a film forming resin, a curing agent and a luster color pigment, wherein the film forming resin comprises an acrylic resin emulsion, which is obtainable by a two-stage emulsion polymerization, and which has an acid value within a range of from 1 to 30 mgKOH/g (as a basis of the solid resin content), a hydroxyl value within a range of from 10 to 150 mgKOH/g (as a basis of the solid resin content), and a particle size within a range of from 20 to 140 nm, and the curing agent is an aqueous dispersion of a hydrophobic melamine resin having a particle size within a range of from 20 to 140 nm.
