What color is glow-in-the-dark?
Why Glow in the Dark Things Are Green. There are two main reasons why glow in the dark stuff mostly glows in green. The first reason is because the human eye is particularly sensitive to green light, so green appears brightest to us. Manufacturers choose phosphors that emit green to get the brightest apparent glow.

Does glow in the dark need UV?
The best way to charge glow in the dark objects is with ultraviolet light (Blacklight). Ultraviolet light has a shorter wavelength than visible light so it can penetrate the phosphor more deeply. This means that more of the phosphor's atoms are excited and emitting photons, resulting in a brighter glow.
