Black Suit for Business?

Black wool is for formal wear.  Black and white is striking at night, but in the daylight black is too severe for the complexion of most men; suits in blue, gray and brown are much more flattering for the majority of complexions.  Futhermore, dark blue, charcoal and dark brown are a much better accompaniment for the shirts, ties and shoes that a man is likely to wear in a business setting.
