The present invention provides for a nail polish composition that is filled into a nail polish bottle, wherein the composition comprises a first nail polish layer comprising a first coloring material, which exhibits a first characteristic color, dissolved therein, and a second nail polish layer comprising a second coloring material, which exhibits a second characteristic color, dissolved therein. A first film layer formed over the first nail polish layer separates the first and second nail polish layers. Also, the first and second nail polish layers are disposed in the nail polish bottle at an angle relative to each other. In this manner, the first nail polish layer and the second nail polish layer are immiscible. Also, the first coloring material is insoluble in the second nail polish layer； and the second coloring material is insoluble in the first nail polish layer. Further, agitation of the nail polish composition causes the first and second nail polish layers to form an emulsion. The emulsion exhibits an apparent color that is different from the color of the first or second nail polish layers such that the apparent color is formed by combining the colors exhibited by the first and second coloring materials.
