As the title says, do you know of any mods for NV which revert the colorization to the FO3 style? I know NV is not supposed to look like that but I'm missing that greenish look a lot.

I know what you mean, it took me a while to get used to the Mojave.

If you follow the configurations shown in this image you should get pretty close to FO3's color scheme: http://static.newvegasnexus.com/downloads/images/40179-2-1297129045.jpg

Here's the links to all of the mods you'll need;
-http://www.newvegasnexus.com/downloads/file.php?id=34868 (Make sure to download "FNV Enhanced Shaders Lite")
-http://newvegasnexus.com/downloads/file.php?id=39619
-http://www.newvegasnexus.com/downloads/file.php?id=39947
-http://www.newvegasnexus.com/downloads/file.php?id=35998 (Make sure to download "NSkies URWLified")

Once you get all of those loaded, configure CINEMATECH and IMAGINATOR in-game as shown in the VIsual Concoction Cookbook image I linked, and you should be all set.

Exactly what I was looking for, the image you posted looks very promising. Thanks a lot, I'm definitely going to give it a try.

No problem, I'm glad I could help.
I also kind of hated the default lighting at first, but now, oddly enough, I actually enjoy it.
