The color is from the potassium !
When flame tested, Sodium ions range from a yellow to a bright orange flame and Potassium ions give a lilac or light purple flame. Neither the Sulphate nor the Chloride ions should have emission spectra in the visible range.
The flame color of ferrous chloride is typically a yellow-green color. This color is due to the presence of iron in the compound, which emits light energy in the visible spectrum when heated in a flame.
violet
When magnesium chloride is burned, it produces a white flame. This is due to the high energy levels of the burning magnesium that emits visible light in the form of white light.
A fire can appear purple when certain chemicals or minerals are burning, such as potassium salts or rubidium chloride. The purple color is due to the unique way these elements emit light when they burn.
A lila color, from potassium spectral lines.

Potassium ions will emit visible light when excited, for example during a flame test. We see this as a lilac colour.
When burned, potassium produces a lilac or light purple flame, while calcium produces an orange-red flame. These distinct colors can be used to identify the presence of these elements in a flame test. The differing colors are due to the specific wavelengths of light emitted when the excited electrons in these elements return to their ground state.

When you burn potassium, it produces a lilac or light purple flame. This color is due to the excitation of electrons in the potassium atoms as they release energy in the form of light. The specific color emitted is characteristic of the element potassium and is often used in flame tests to identify its presence in compounds.
The specific wavelength of light for potassium chloride depends on the energy level transition of the atoms or molecules within the substance. In general, potassium chloride exhibits absorption or emission lines in the ultraviolet and visible light regions. The exact wavelength would need to be determined experimentally or calculated based on the electronic structure of potassium and chloride ions.
The flame colour should be LILAC. When holding the potassium chloride above it, make sure nothing has dropped into the flame/Bunsen Burner before as that will definitely affect the results (i.e. change the flame colour completely!). It can turn out to be pink or white, but it should be lilac, so don't worry.How to do:1) Select a splint or tweezers/safe holder and soak in compound.2) Gently pass the splint through the hot flame of a Bunsen Burner. Do not hold the splint in the flame for too long, as it could affect the results.3) Return the splint and wash thoroughly before reusing for different compound or experiment. Wash hands if any substance causes irritation or harm. Do not rub eyes as all chlorides are irritant, corrosive, toxic or harmful.
