For the job interview is a charcoal colored suit acceptable? Actually, I guess I want slightly more than acceptable, would it be considered within the norm? Basically I want to look like everybody else and not be "that guy" in the goofy colored suit who they talk about behind closed doors.

I ask since a friend who interviewed told me that his entire interview group wore navy or black, and when A.K. did his morning greeting he made a positive mention of something to the effect of "glad to see everybody got the memo on what to wear..." Not trying to make a big thing out of nothing, but the opportunity is too big to mess up over the color of my clothes .
