Blue or pink smoke ideas?

Steaming JonOGR Forum Member

I’ve been toying with ideas for the gender reveal of our next child. I was intrigued by a Facebook post showing someone using the real MILW 261 (4-8-4 steam loco) for their reveal... I don’t have any connections with any real steamers, so I can’t copy that, but I do have an Atlas industrial rail 4-4-2 with smoke (piston-driven puffing smoke)...

Anyone care to help me brainstorm how I can either make blue or pink smoke, or make the smoke appear blue or pink?

The only criteria is that I don’t damage the locomotive. If a particular method had the potential of causing health issues or staining things inside I could potentially set up and film outside...

FYI I will know in about a month which color I will need...
