I've been playing around with the gold ship editer and it appears that light grey (white) and dark grey (high intensity black) display reversed within the editer. When I view the ships in Swath or Attac the colors appear correctly. I'm not sure if this is a bug in the ship editer or if there's a problem with how windows mapped the colors for the editer window.
On a side note, I also tried Zoc 5 and white and intense white seem to be reversed. So the ISS shows up as light grey on blue instead of white on blue.
Its ZOC. I cant explain it, but I have seen Ships that were white in swath look Orange in Zoc. Somebody else may be of better help tho
