A mixed powder composition is of approximately 25% photoluminescent pigment and 75% binder. The photoluminescent pigment may include chemically doped metal sulfides, alkaline earth metal aluminates or alkaline earth metal silicates that are activated by light and generate a long after glow of light that glows in the darkness for many hours. The photoluminescent pigments are carried by a binder mix such as drywall mix (mineral gypsum) or plaster of Paris (calcium sulfate semihydrate). The powder is sprayable from a bottle with a nozzle onto tree bark, rocks or the ground. As the powder absorbs moisture, it becomes hard to last for months. The photoluminescent pigments in the soft or hardened powder absorbs sunlight or ultraviolet light from a flashlight to emit a long after glow to assist the user in navigating in the dark wilderness.
