Okay guys, here’s the story. Business ties look funny with a sexy tuxedo, no matter what color they are. The purpose of the bow tie is to look whimsical instead of scary like a black business tie does. Think undertaker. Black has many personalities, and one of which is forbidding, like Gestapo, Mafia, so that’s why bow ties are de rigueur with a tuxedo. Who wants to look threatening when you can look sexy in a tuxedo!
