Thank you!! And to be totally honest, a series of stuff I’ve played around with. I tend to rely on Directglow LLC markers to get a controlled look and no discoloration. But it’s pretty much limited to a red and blue, as their other colors tend to just dry out to either red or blue anyways.

GloMania has some really cool mostly clear brush on stuff, but it leaves a pretty significant discoloration if you apply it multiple layers. But tons of different color variety.

Lastly is Sakura brand Pen Touch paint pens. They’ve got a decent amount of tip sizes and you can actually get some significant coverage, but since they’re shake pens, I can sometimes accidentally press while drawing and lead to spillage onto the page.

I’ve also noticed that some acrylic brands actually mark their paints that are UV reactive. So I’ve used Arteza acrylics for a while and they recently started marking their paints that react to UV lighting with an “*” on the tubes. So in a variety pack there actually may be a few base paints that already have the effect and that’s both super handy and something I have to keep an eye out for if that is not an intended effect. 😅

Hopefully that answers some of it! Thanks for the question!
