UV light/black light

Hello everyone,

I’m pretty new here so I don’t if I’m in the right category to ask this question but anyway.

I have a project were I’m doing creating a little crime scene, with two different lightning. The second lightning is my problem I would like to make a post process recreating a uv light (with print who appear when uv is on) but I have no clue of how to do that. Can somebody help me ?

(Btw sorry for my terrible English not my first language)
