My partners in crime (Eric Squires and Shane Ireland), have had a good deal of tongue-in-cheek fun trying to reconcile a color generally referred to as "anthracite", presumably due to its resemblance to, well, anthracite, with a series called Aero, suggesting flight. As Eric queried, "Airborne coal? Whoever heard of such a thing?" Well, I, your long-suffering and deeply abiding describer since 2005, have sussed out the secret answer: clearly this specific color/series combination is homage to the F-22, B-2 and F-35 Stealth aircraft! No, seriously. Am I right? (dead silence, save for the chirp of a cricket in the background).
