I came along in the 90's as a star wars fan (was born late 80's) so when the SE's came out, that's what I'm use to... although I will admit, I enjoyed watching the ORIGINALS on VHS... I loved Return of the Jedi ... lol... didn't EVER watch Empire...and A New Hope was a good stand alone film. heh
I liked the cover art for ROTJ heh...
Where I'm going with this is I was use to the micromachine Tie fighter, which was about that color as well. If I had to say a paint color, I'd say "Gunship Grey with a bit of white added to lighten it." I once was painting a model of the USS Voyager, and that was the grey I used... and it's that sort of blueish grey... it can look both colors depending on the lighting...
