Why LiCl acquires pink colour when heated in Li vapours

Hi,
When a crystal of LiCl is heated in an atmosphere of Li vapour, the Li atoms lose electron to form Li ions. The released electrons diffuse into the crystal and occupy anionic sites ( F-centres ) . These electrons impart pink colour to the LiCl crystal.
Hope this helps.

Answer:
Because of F centres.
Explanation:
When Lithium Chloride in crystallised form is heated with lithium vapor, Lithium atoms lose electrons to form lithium ions. The released free electrons occupy the anionic sites known as F Centers. The pink color is formed because of the exciting of those electrons when they absorb energy from visible light falling on them
