Here’s where your creativity

Here's where your creativity may come in handy.  I recommend experimenting with the suggestions here. 

There's also a very inventive music video by Sia "Soon We'll Be Found", that uses light in great ways (including black light) you may want to check out.  They use florescent paint in part of the song, on the faces.

I still believe that spot lighting may prove to be your best bet.  That said, I wish you the best of luck!
