The characteristics flame test color of metals ions are due to atomic emission spectra.

Explanation:

When an atom absorb a specific wavelength radiation, the electron inside in it, move from lower energy level to higher energy level. Such a process is known as absorption. When this excited electron come back to its ground state, it loses energy in specific color depending upon the frequency of absorbed radiation. Such a process is known as emission .

Energy level:

As an atom has different energy level, the level near to nucleus has less energy as compare to level that are far from nucleus. So electrons move from lower energy level to higher level by gaining specific energy, and after excitation it come back  from high energy level to low energy level with emission of light.

Planck's Concept

There is specific energy difference between two energy level, so such energy difference is quantized. only those radiation will be absorbed that are equal to the energy difference between two level.
