I have been burning brain cells on this for a while. I do have one final
question. Like in the case where there was green in all sorts of places, how
could I go and change all the green areas to any color that I want, in only a
couple of clicks?

This is pretty simple in terms of getting the selected area with this
Load the image into gimp.
Choose the color selection tool.
Set Threshold to 30
Click on the darker green area.
At least for your sample map, that got everything. Note that the color on your
sample map is not uniform, which is why the threshold has to be upped from the
default (15) to 30. If it doesn't get everything, start over (undo the last
operation or exit and start over), up the threshold some more and click on
missing areas until you get them all. This works relatively pain-free because
there is no similar green anywhere in the image.
Edit/Copy to copy the selected area.
Select/None to deselect everything
Click to expand "Advanced Options"
Set "Fill with" to transparency
You should have just the green areas
Close the window containing the original image
If you don't have the layers dialog open, bring it up.
You should see a "Floating Selection"
Click the anchor button along the bottom (next to the trashcan) to anchor the
pasted stuff into the background.
