Luminous paint

Luminous paint glows in the dark. It is often achieved through a coating which contains a pigment called phosphor, though usually a form of zinc- or calcium sulphite. The result is the appearance of storing light which radiate a greenish or blueish glow after the light source has been removed. Luminosity should no be confused with fluorescence, though they share many commonalities. Daylight fluorescent paint glows normally in daylight, but in contrast to luminous paint, it must be activated with ultraviolet paint to emit its glow.
