Any paint that contains a luminous pigment. Fluorescent colorants appear to glow or luminesce in daylight because they emit greater than 100% the visible incident radiation. Additionally, many of these colorants glow in ultraviolet or black lighting. Fluorescent paints usually contain a base of calcium, strontium, or barium sulfide that is spiked with traces of other metal salts. These salts absorb energy from light and remit it in the form of photons. New fluorescent dyes are also used. Fluorescent paints were first sold in 1934. They are used in operating rooms to brighten the light intensity, on road signs to make them more visible in the dark, in advertising to make boxes and adds appear brighter and as a decorative paint. One popular brand, Day-Glo® paints, produces decorative colors in bright yellow, orange, red, blue, and green. These paints are not lightfast enough for use in fine art painting. Several color changes can occur with time, such as decreases in the intensity of the fluorescence and/or fading of the colorant (Ellis, McGlinchey and Chao 2000).
