Summary:The present invention relates to a cosmetic pigment composition exhibiting colors in the visible region, which comprises an effective amount of nanoparticles or a mixture of two or more nanoparticles selected from the group consisting of (a) gold nanoparticles exhibiting red color; (b) silver nanoparticles exhibiting yellow color; (c) gold-silver alloy nanoparticles exhibiting flame color; and (d) gold nanoparticles exhibiting blue color, and a color cosmetic composition and a color lotion comprising the pigment composition. According to the present invention, it is possible to prepare pigments exhibiting various colors in the visible region using gold or silver nanoparticles, and a cosmetic pigment composition which can exhibit various colors by mixing the pigments in various compositional ratios, in which precipitation or agglomeration of particles does not occur, and whose color can be maintained for a long time. Also, since the pigment of the present invention is not harmful to the human body unlike conve
