A method of manufacturing a multiple-color plating member includes forming a copper plating layer on at least a part of a surface of a substrate, forming a nickel plating layer on a surface of the copper plating layer, forming a chromium plating layer on a surface of the nickel plating layer, applying a color coating agent onto a surface of the chromium plating layer and then drying the applied color coating agent to form a color coating layer, and applying a clear coating agent onto a surface of the color coating layer and photocuring the applied clear coating agent to form a clear layer. The color coating agent includes 10 to 35% by weight of a modified acrylic resin, 1 to 25% by weight of a pigment, and 40 to 80% by weight of a first solvent. The clear coating agent includes 10 to 30% by weight of a polyester-modified acrylic resin, 5 to 25% by weight of an acrylic oligomer, 5 to 45% by weight of an acrylic monomer, 1 to 15% by weight of a photoinitiator, and 10 to 75% by weight of a second solvent.
