PROBLEM TO BE SOLVED: To prevent precipitation and flocculation of a coating material, to improve appearance and to obtain a new design by using a colorant also useful as a coating material which does not need the preparation of a primary color for each kind of coating material, has a sharp particle size distribution of fine particles, and is uniform in the particle size and particle size distribution of the each primary color. SOLUTION: This colorant also useful as the coating material is obtained by subjecting a pigment and a metal in a dispersing agent obtained by combinedly using water, a solvent, an activator or water, a solvent, an activation and a resin to shock wave and plasma dispersion, has particle diameters with a central particle diameter prescribed in the range of 0.01μm-20μm in which the particles having the central particle diameter amounts to≥20% of the whole dispersion pigment and the range of particle size distribution is within the central particle diameter±80%.
