This is the scientific explanation for the effect: Quoted: "Many kinds of color phenomena (particularly in gems and metals) arise because the incident light is absorbed by atoms, and this disturbs the electrons in various ways that create the apparent color. fluorescence arises in natural materials for several different reasons. In the case of fluorescent paints and inks, the incident light disturbs the atom sufficiently to cause it to emit a photon in response, usually at a different wavelength than the light absorbed. At the same time, the paints or inks absorb or reflect light in the way normal paints do. the "fluorescent" effect arises in the wavelengths that are emitted from the atom, rather than reflected, causing the "glowing" effect." Bottom line is that in order to get the effect that you want you will need the proper ink or paint because the paint is actually emitting light. The next best approximation is as bonestructure suggested. The following link will allow you to obtain the RGB colour values of fluorescent paint with the eyedropper. http://www.goldenpaints.com/products/color/unique/fluor.php Shane
