This pigment has been around forever, and I'm sure a few of you out there will have to confess that you had at least one or two black light posters during the 60's and 70's. Well, we sell the raw pigment so that you can make your own fluorescent paint. Add these pigments to a little of our Art Medium Type A and you've got it. Actually they're compatible with a lot of media, the only restriction is that they won't work in lacquers or paint systems that contain ketone solvents (the pigment swells and becomes ineffective). Otherwise, go for it and create some posters of your own and break out the old black light. Far out! Essentially what you see is what you get, except in the case of the invisible blue, which is invisible/white except under ultra violet light.
