Impact on CIBIL Score from Closing Shared Limit Card?

Credit Card ICICI Bank Credit Card

I have three ICICI Bank credit cards with a shared limit: one Coral and two Sapphiro. If I close the Coral card, will it affect my CIBIL score, or will there be no impact since the limit is shared?

@ArunDas It largely depends on the age of the card. I recently closed my TataNeu Infinity card, but since my Regalia card(my oldest card)is still active, there was almost no impact on my CIBIL score.
