Lee,
Check out theses pictures:

The top picture in the group is taken from Skyline drive in Virgina. Others are from Cades Cove in Tennessee a bit further south but they all fit together well and will give you a feel for what you are wanting. A "smokey" outline for the hills in the distance is all you need.
Light blue for the sky; blue-gray for distant hills; second coat closer hills with blue-green for trees.
If you have a large area to cover then you can get the paint store to custom mix a quart to the final colors you choose.
Good luck,-John
Flat house paint works fine. Those 2oz bottles of craft paint are good for the scenery too.

This thread might give you some ideas. Jarrell did a fantastic job on his.
I thought to just use one shade of blueish-white paint for the backdrop. Not being an artist, I don't really want to fiddle w/ different shades of paint. I think that backdrops shouldn't focus attention away from the operations, but do want to give the imrpession of 3-D. Here are my questions:
1. Should I get latex flat paint?
2. How to easily convey hills or the Appal. mountains? I want to depict a spring day in Soutern VA. Anyone who is from, or visited there, knows it gets somewhat hazy. If that is easy to do, great. Otherwise, I can just stick w/ the one shade of light blue.
Ideally, I want to do the backdrop once and move onto other things!
Cheers,
Lee
