The flame test in analytical chemistry is only qualitative.
Cesium burns with a lilac or bluish-violet flame in a flame test.
The flame test for nickel produces a blue-green color flame.
Cobalt gives a blue flame test while chromium gives a green flame test.
Chlorine gas itself does not emit a colored flame when subjected to a flame test. Instead, it will impart a green color to the flame when a sample containing chlorine (such as a chloride compound) is included in the flame test.
It is not the anions (e.g. iodide) that are responsible for the flame test color, rather the cations such as sodium ion, potassium ion and calcium ion give you different colors.
