To produce colored particles with a 10-200 µm average grain size simply, efficiently, and in high yields, in order to obtain suede-type paint constituents with excellent decorative features capable of producing finely detailed, marble-like, multi- color patterns. Water-insoluble particles and a polyvalent carboxylic acid resin with an acid value (solid-based) of about 20-120, either water-soluble or water-diffusing are mixed in water; and after primary coated particles are formed on the surfaces of the water-insoluble particles on which the polyvalent carboxylic acid resin is adsorbed, a dispersion-stabilized emulsion resin containing a colored pigment is mixed in the dispersion liquid; and a metal salt is added to this mixture so that colored particles with an average particle size of about 10-200 µm with a surface colored coating are obtained. The water-insoluble particles can be either synthetic resin particles or inorganic particles.
