Here are some examples.
A lot of Halloween decorators report problems finding fluorescent blue spray paint.
Krylon makes a fluorescent blue spray paint, #3109.
If your store does not carry it, ask them to order some.
Warning: The glow color of fluorescent paint is not necessarily the same as the daylight color. Most red day-glow paints actually glow orange under black light. Do some research before you buy.
Invisible black-light paint is merely invisible under normal lighting. When the black light hits it, it springs into vibrant color!
Note - Invisible black light paint dries clear, or with a slight milky haze to it, depending on the brand, thickness of applied layer, and color of the black light glow. Some brands look like white paint until the black light hits them. Since these aren't really transparent, I wouldn't consider them to be really "invisible", but they might be sold as such. Ask before you buy.
The potential for this material is to bring about a sudden appearance, disappearance, or transformation. Consider the simple case of a blank white wall in a dimly-lit hallway. When your guests reach the middle of the hall, they see that the walls are suddenly spattered with red blood, perhaps spelling out a spooky warning. A moment later, the red spatters are gone.
Another trick is to take a painting and doctor it up with invisible black light paint, so that it transforms into something sinister when properly illuminated. In order to get the full effect, you should use the transparent paint, so that in normal light, all you see is the painting.
Another thing to look for is RIT-brand fabric whitener and brightener. It should be in your supermarket with the fabric dye. Essentially, this is pure concentrated optical brightner, and fluoresces a strong blue-white, even in tiny quantities. Under white light, RIT is completely invisible. It is available in powder or liquid form. The powder can be used as-is, for dusting, or mixed with water for a spray.
You can make your own UV-sensitive paint by mixing RIT-brand fabric whitener and brightener with just about any commercial paint, lacquer, or varnish. If the paint is water-based, you can use the liquid RIT. If the paint is solvent-based, use the powder RIT. The ratio is not critical - anywhere between 1:5 and 1:20 (RIT:paint).
Avoid mixing RIT with acrylic materials that are intended for use outdoors, or claim to be "UV stabilized". The chemicals in such materials prevent the UV light from getting to the RIT, so it kills the glow. When in doubt, mix a small batch and test with your black light before using it in quantity.
If you want color, you will probably want cheap poster or tempra paint, in fluorescent colors. You can get tiny pots of them in craft stores, but the prices are a lot better by the pint at art supply stores.
Warning: Do not attempt to improvise fluorescent makeup. Some people have reported allergic reactions when they tried to smear Woolite or Rit on their faces!
This hair spray says that it glows under black light,
but doesn't claim to be phosphorescent.
This is a package of the powder form of Rit brand Whitener and Brightener.
I think I picked this up at
This alien-themed GITD paint was marketed shortly after the release of the movie Toy Story 2.
This GITD spray often turns up around Halloween.
I think I got this sample at
I think I found this GITD makeup during Halloween 2002.
Only use makeup that is designed for to be used as makeup. Such products are usually safe. But even then, be on the lookout for signs of possible allergic reactions.
For some reason it is difficult to get a good red color under black light. Most fluorescent red paints actually glow some shade of orange under black light.
Do some research before you buy. Make sure you have the color you want before slathering it on a prop! When in doubt, take a battery-operated black light to the store when shopping.
This has never worked well for me. I suspect that the electronic transitions that make fluorescence possible result in monochromatic light that is hard to change.
Liquids can be brushed, rolled, or sprayed, depending on how thick they are. (We used a compressed-air paint-sprayer to cover our giant spider.) Powders can be dusted on, a famous trick to add a glow to spun spider webs.
Some of these colors, especially the RIT, are very hard to get off your hands. You might get the visible stuff off, but under black light, you'll light up like a Christmas tree.
If you are painting on-location, watch out for overspray, dripping, and other clever ways to put paint where it doesn't belong. If you are painting under white light, you might not notice until too late that you have gotten a fierce glow where it should not be!
If you leave black-light-sensitive props out in the sunlight, plan on repainting them regularly. Black light pigments are delicate and fade rapidly.
