A display system for blending two (or more) light systems. The system includes an object with an outer surface. The display system includes a light source projecting ultraviolet (UV) light onto the outer surface and a light source projecting (concurrently in many applications) content onto the outer surface with visible light. Further, the display system includes a light-blending element on the outer surface for concurrently receiving the UV light and the visible light. The light-blending element includes a background layer reflecting the visible light and a foreground layer covering at least a portion of the background layer and producing light in response to the receiving of the UV light. The foreground layer includes black light paint that fluoresces to produce the light in response to the UV light. The background layer includes a layer of material that is non-fluorescent in response to the UV light such a non-fluorescent white paint.
