The color of the flame test is specific for some metals.
See the link below.
You can use a technique called flame test where the substance is heated in a flame. The cations present in the substance will emit distinct colors of light based on their unique electronic configurations. By comparing the observed color with a reference chart of known cation emissions, you can identify the cations present in the substance.
It is not suffiecient to identify a cation only on a flame test.æ You must also identify the color of the flame which corresponds to a certain element.
just looking at the color of the flame --- qualitative
With the flame test we can identify some chemical elements; see the link to Wikipedia, for ex.
to identify an unknown sample by its emission spectrum
1. not all elements give colour to the flame 2. flame test is not always accurate

It is usually used for when one is trying to figure out the chemical make up of an unknown substance. Depending on what color the substance makes during a flame test will help you figure out what it is composed of.

If no color is produced in a flame test, it typically means that the substance being tested does not contain any specific metal ions that are known to produce distinct colors in a flame. This could indicate that the substance is a non-metal or that it belongs to a group of metals that do not exhibit flame colors.

The color of the flame is indicative of the constituent elements.
to identify atoms present on an element

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.
Its like Mg, it has no colour. So bright light
