Can a Groom wear a different colour suit to the Groomsmen?

I am wearing a mid grey tailcoat with white shirt, silver waistcoat (To match bridesmaids) and white cravat (To match Bride) and my groomsmen (Best man, 3 ushers and father of the bride) black tailcoat with same shirt, waistcoat and cravat. Is this acceptable!?!? Thanks!
