I have been looking at mine closely this evening and here is the best way I know to describe it: The roof is painted a dark green and then it looks like black was applied over it to give it a weathered appearance (it is a technique I use often in my other hobby of model railroading). I believe the same thing may have been done to the door and windows as well except that so much black is there in these areas that the green really does not show. It will likely be this weekend before I can take pictures and upload them but I will endeavor to do so.

Regards,
