flame coloration is a test for the Metallic ion because the metallic ions will enter an exited state and release photons energy, in the form of light, as they return to their ground state.
cations cause the color change
Test another salt with a different anion but the same cation. You will get the same flame color.
it doesnt change the color of the flame.
I presume you mean silver nitrate. A flame test detects only the metal ion in a compound. There isn't one for silver.
Blue
The colour of any sample containing copper ions burns with a bluish green flame in the flame test.
All sodium salts will give a yellow flame test, because of the metal sodium in the compounds.

red. crimson.
Flame test. Dip a piece of platinum wire into concentrated nitric acid, and then roll it in the sample. Put the wire over a Bunsen flame. If a lilac flame is observed, it is potassium nitrate.

It depends on the conentration, did a test today with several nitrates (incl. lead nitrate) and they were all yellow/orange...

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.
If you have the solid of whatever your testing and you burn it (flame test) it will burn with an orange flame if sodium is present. To establish whether it is sodium CHLORIDE, ad a solution of what your testing to silver nitrate and it should form a white precipitate if it's sodium chloride.
The color of lithium in the flame test is red.
