An apparatus, system, and process for demarking a control object using direct non-visible light is disclosed. A non-visible light reactive compound is applied to the control object. In one embodiment, the non-visible light reactive compound forms a designator. A non-visible light source directly radiates the non-visible light reactive compound. The non-visible light reactive compound reacts to the non-visible light by radiating visible light, illuminating the non-visible light reactive compound. The illuminated non-visible light reactive compound demarks the control object. In one embodiment, the non-visible light source is an ultraviolet light source and the non-visible light reactive compound is an ultraviolet reactive compound.
