Oh, I'm with you there. Charcoal has always been considered the other preferred color for interview suits. What you should avoid is light navy, light gray, brown, etc. Too informal. And black is for a night on the town or a funeral. Not for business.
Generally cannot go wrong with Navy Blue or Charcoal. Further - I posted "wear what you're most confident in". ATN was correct though - the "standard" is Navy or Charcoal. Why be a test pilot? Where whatever you are most confident in - between Navy or Charcoal.
