(Rather than bump that old thread, I'll just hijack this one now that it's served its purpose.)
I had a question for anyone who has experience modding map colors: Is it possible to do anything with "Clear" (Plains color, as well as the default color in most of the other mapmodes). I can't find it in any of the gamefiles, and I'd like to toy around with replacing the bland vanilla color with something a little more "plainsy". It'd be extra nice if there was a way to mod the plains color while leaving the rest of "Clear" alone for the other mapmodes.
Are either of these things possible?
