Obtain color-changing ink or dye Measure out a small amount of dye or ink. One-eighth of a teaspoon should be sufficient. Use the small funnel to add the dye or ink to your clear or white nail polish. Before doing this, you may want to pour out a little nail polish from the bottle so that it won't overflow. Mix your nail polish with the brush that comes with the bottle. You also could close the bottle and shake it to make sure the color is thoroughly blended. Add more dye or ink until until you have the color you desire. Add only a little at a time.
