If they ever invent a fluid that emits black smoke when heated, I'll start using it in my diesel engines.
I can give you the black smoke right now. However, I am NOT available for the massive cleanup you'll be doing when the black particulate settles on everything around the layout! The reason you don't see black smoke is that it would have to be particulate matter, and that would make a massive mess! The white "smoke" is simply mineral oil vapor, while it does settle, it takes a lot of running time for it to be of significant impact.
I wonder if 50% food coloring added to smoke fluid would produce different colored smoke ….and no, I won't be trying it and letting you know.
