it will form a yellow precipitate
white :] To be sure, search this on Wikipedia, and look to the right at appearance.
They are not soluble, therefore they do not precipitate or form a color....a.k.a....no reaction...

Potash stiffens the stems and improves colour.
Chloride and iodide ions can be distinguished by the colour of their precipitate which are formed by treatig it with silver nitrate solution.
Due to the potassium ion in potassium nitrate, any firework composition made with potassium nitrate would sport a purple/violet color, unless a strong colorant compound like strontium chloride is added to the composition.
The colors come from metals the react with heat. here is a table of the what metals give out what colors.

This compound is potassium chloride.
Yes it is a precipitate, generally yellow in colour
In a flame test, potassium and its compounds emit a lilac color, which may be masked by the strong yellow emission of sodium if it is also present. Cobalt glass can be used to filter out the yellow sodium color. The potassium ion is colorless in water.
Strontium carbonate is a white powder.
