None. Using flame spectral analysis, we can use a prism or other device to determine the color of various metals. Nitrate gives no color. The purpose of the test is to give metal detection, qualitatively. Testing for nitrate is another test, not involving flame.

Lead nitrate
Potassium nitrate is ionic because the "nitrate" is an ion. Nitrate produces a NO3- ion (negitive ion) and the Potassium produces the K+ (positive ion). Thus the ionic designation.Enjoy
Nitrate ion is NO3-1 while Nitride is N-3.
The polyatomic ion in KNO3 (potassium nitrate) is NO3- , the nitrate ion. This ion is polyatomic because it contains four atoms bonded together. The nitrate ion is derived from nitric acid, HNO3.
The nitrate ion concentration affects an equilibrium, because it does this, it makes a more colorful ion change that is concentrated.
The nitrate ion is the oxidizing agent in the compound without it you could not burn the chemicals and you could not produce a spectrum so there would be no emission of color

The nitrate ion imparts no color to a solution.
The nitrate ion is NO3-
The nitrite ion has one less oxygen atom.
Nitrate: NO3-
