I believe this is the one that Cham3I3on is talking about:
The lighter gray on the mid fuselage which sometimes extends onto the inner wings and to the engine nacelles is the only major difference from the basic Ghost Gray scheme from 1990.
After looking at alotta recent shots of Hogs it seems that there are/were many variations of this scheme, as is usually the case. Some didn't have the lighter gray at mid-fuselage at all. It probably differs from unit to unit.
The basic colors as shown on the Don Color page are correct, just make sure you research the aircraft you're building. If it's important to you, that is!
Fade to Black...
