Reaction of Li with H2O
Lilac to Purple-Red
Potassium has a violet color in the flame test.
The flame color of lithium is a bright red, while the flame color of potassium is a lilac or light pink. These colors can be observed when the metal salts are heated in a flame, causing the electrons to jump to higher energy levels and then emit light as they return to their original state.

Lithium salts, such as lithium chloride or lithium carbonate, are known to produce lilac flames when burned. This color results from the excitation of lithium ions in the flame.
Potassium has a violet color in the flame test.
lilac
Potassium has a 'LILAC' ( pale purple) flame. Group (I) metals Lithium = Red Sodium - Yellow Potassium = Lilac. NB Other metals have coloured flames. Copper being the most well known , with a blue/green flame.
Cesium burns with a lilac or bluish-violet flame in a flame test.
Lilac to Purple-Red
When potassium metal reacts with water, it produces a lilac-colored flame. This flame color is a result of the energy released during the chemical reaction between potassium and water.
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.
Potassium ions will emit visible light when excited, for example during a flame test. We see this as a lilac colour.
well , the colour of potassium chloride is a lilac colour :) hope this helps
