Zusammenfassung:	A manufacturing method for a resin product having flow patterns uses a resin material, which is obtained by compounding a base material having a given ground color and a colorant having brightness different from that of the ground color. An injection-molded article having the flow patterns is obtained by injection-molding the resin material by means of an injection molding machine. A colored clear layer having a color different from that of the base material is spread over the surface of the injection-molded article. The resin product having the flow patterns that are adjusted to a desired product color is obtained by combining the respective hues of the ground color of the base material and the flow patterns and the hue of the colored clear layer.
