Hello. The set designer for our next production wants to explore UV/Blacklight paints. She would like to paint a whole set and use it for one act. I am aware that rosco and wildfire sell those kinds of paints, but I know that they are pretty pricey. Are there any less costly alternatives? How effect are they? How can I make the actors be seen, I know that it has to be pretty dark on stage in order for the Blacklight to pick up the paint. Thanks!
