WHY FLUORESCENT COLORS?
Although fluorescent ink does not glow in the dark, it DOES glow very intensely under so called (UV) black lights as it reacts to long-wave ultraviolet (UV), commonly known as black light. Through the mechanism of fluorescence, UV-sensitive pigments present in the paint absorb the ultraviolet black light (invisible to the human eye) and give off visible light in return. Fluorescent paint appears a bright neon color under normal daylight or other visible light, and glows brilliantly under black light. Most fluorescent prints are highly used in both for costuming and stage attire.
