Ok here's the situation.
I fly radio controlled turbine powered jets.
Hooked up to the rear of the motor is a spray nozzle where I mist low viscosity mineral oil.
When the mist meets the exhaust at 650C it turns into a huge white smoke plume.
Now what I would like to do is to turn that smoke to different color.
Is it possible?
Red, blue, black?
Is there a chemical that will vaporize at a selected color?

as it is the gas that itself is colored, you now have a search keyword :)

Remember, gases are not computers. You cannot say, "Ok, I would like you to turn purple at 30 degrees."
-
I'd say your best bet would be to add a chemical that forms a powderous or liquid compound of apparent colour when oxidized rather than trying to get a coloured gas. All coloured gasses I can think of are pretty nasty things...
-
To achieve different colours upon selection, I think you have to install different mist emitters for the intended colour.

ok after doing some searching what about this.
Starting with a base of mineral oil which vaporizes white, what if I add the following:
Solvent Violet 13 for Viloet smoke
Solvent Blue 35 for Blue smoke
Quinoline Yellow SS for Yellow smoke
Sudan Red G for Red smoke
what are the pros and cons?
Will it even work?
Where can I get these dyes?

Google color smoke fireworks.
