Photochromic inks change color when exposed to ultraviolet light usually from the sun or a black light. The inks are effectively colorless indoors and turn into vibrant color outdoors. When brought back inside, the inks become clear again. The inks become intensely colored after only 15 seconds in direct sunshine and return to clear after about 5 minutes indoors.
