No they are sort of medium grey, they just look charcoal in that picture.
Have you ever been able to size down from a 46L? I'm also a 44L and recently found a 46L Samuelsohn SC for 40% of retail that fit for length and sleeves. If the shoulders weren't absolutely perfect they were very close. The jacket is being slimmed through the body and I can pick it up in a week. I've been told that Sameulsohn is a good brand when it comes to alterations but I dunno as the guy who told me that was a salesman.
