HEYA!!!
HERE IS YOUR ANSWER,
⇔ Well the reason behind this is :
→ The Cl⁻ ions diffuse to the surface and form LiCl with Li⁺ ions. An electron is released which diffuses into the crystal and occupies the anionic site.
→ Such anionic sites occupied with electrons are called F-centers. These impart pink color to the crystal.
→ The color results by the excitation of the electrons on absorbing energy from visible light falling on the crystals.
HOPE IT HELPS YOU,
THANK YOU. ^_^
