The present invention provides an aqueous colored base coating composition (A) comprising a hydroxyl- and carboxyl-containing acrylic resin (A-1), a melamine resin (A-2), an alicyclic epoxy-containing compound (A-3), a neutralizing agent (A-4) and a coloring pigment (A-5). The present invention further provides a method for forming a topcoat which comprises applying the aqueous colored base coating composition (A) to a substrate and applying to the base coat an organic solvent type clear coating composition (B) to be cured by the crosslinking reaction between a carboxyl group and an epoxy group.
