Pigments having magnetic properties are manipulated using magnetic fields to produce color patterns. The color patterns may be created in a medium such as a molten plastic or a plastic solution. Once disposed in the flowable medium, the pigments migrate by the influence of magnets after which the pigments remain static due to the drying and/or hardening of the medium. A molded plastic article comprising oriented effect magnetizable pigments is provided. The article may be used to contain cosmetics, personal care products, or foods.
