Blue

*Updated 7/29/25 - Make sure you have the correct 365 blacklight as referenced by the manufacturer. THEN it looks just like the picture. It does what it says it would, but it is very, very pink. Nowhere close to the red in the product picture. I bought the green and the blue as well, for some reason one of those was opaque white instead of clear. It’s alright, but that’s all. It’s a little bit expensive to feel just alright about the purchase. *Update 6/28/2025 - Important to make sure you have a light source that really does have the 365 wavelength. It makes a tremendous difference.

Not really bright when applied unless you add more pigment or use a special black light at the right wave length

I was honestly a bit skeptical of this product before I bought it. But I knew I could find a million uses for it if worked as advertised. So I decided to give it a chance, and I'm happy to report that it really does work. Looks cloudy and yellowish in the bottle under normal light, but glows a nice neutral red under blacklight. It's very thick, which is great because you can thin it (I'm thinking this is lacquer based) and make a few large batches which will last a pretty long time. I've not tried airbrushing with it yet, but I imagine it'll work as long as you thin it enough. All in all, if you're curious about this, get a bottle and try it out. I'm pretty sure you'll be satisfied with it.

This stuff is good, the color is more orange than it is red, but the glow is there and it's invisible as described. Just be aware that this is a lacquer based paint and not acrylic so you need some thinners for cleanup and flow improvement. But, it can be painted over if you miss, just make sure you have a blacklight/UV light handy to check your work. I'd give it 5 stars, but it came in an unpadded envelope so there is a lot of potential to spill in transit.

Finally got to the point on my painting that I bought this for, and I was very pleased at what I found. I love that shade of blue on a black canvas, and it was easy to control the amount on the brush and it seemed to last a long time before reloading the brush. Great product.

does light up bright red with UV light but the second the light moves the color fades. unlike other glow products it fades immediately.

I use these to paint me fishing lures and weighted hooks so the fish can see them easier. I also have a UV light to test it. Wow. Very very bright and have already upped my fish count due to these.

The blue and red colors are transparent, vibrant, and easy to use without mixing. However, the green one is not as clear, and I’ve found that I need to dilute & mix it the particles to make them work.

Good product, as expected.
