A metalized layer can be added between a light effect material and a viewer so that components creating a light material viewing effect are masked by the metalized layer when the light material viewing effect is not activated. The metalized layer, light effect material and or an article of manufacture incorporating them can be designed so that the light material viewing effect, when activated, enhances a visual design (such as artwork). The metalized layer can be incorporated into a self-contained module or be separately incorporated into an article of manufacture.
