You probably already know that too much black can make (some of) you look pale. But have you considered what it can do to your hair?
Have a look at Rep. Tammy Baldwin in her office last week:
In this case, her face actually doesn't look that pale. But look at her hair: what is usually a nice sunny blond now looks....white. This was the unintended consequence of a lot of black and overhead lighting. Blonds beware!
