- Plain (black)
- Water (blue)
- Forest (green)

A fundamental problem is that the legacy JTCS map labeling system was really designed for text labels, with the code "intelligently" offsetting the text up, down, left or right around the specified Left, Center or Right (relative to hex center) placement. In the screenshot above, you can see where the border '+' are not centered in the hexes, and strangely drift off "center" in seemingly arbitrary fashion.
In Middle East, we added the
- Special (red)

Maddening!
In Vietnam v1.00, we introduced the new
- Border (black)
So far, so good. But what if, in the case of the Week in Binh Long monster scenario for example, you want to use a different color for the various AOs (KENTUCKY, IOWA, LOUISIANA, etc.). You would have something like this

where there are significant gaps in the border display; the '=' are not hex by hex. (If they were, the randomly drifting marker placements would be quite obvious.)
In CSVN v1.20 (and thereafter), for the Border type, we now allow selection of the colors
- Black
- Blue
- Green
- Red
(Note too how, at the request of our Dev Team Cartographer, Jason -- professional cartographer is Jason's Real Life day job! -- we have made the Type changes Plain -> Anthro, Water -> Hydro, Forest -> Natural, leaving Special and Border unchanged.)

With the revised, centered Red border markers, note the after screenshot (compare with the before screenshot above):

Much clearer, much better!
