I disagree, I would like more green/blue/red filter, it adds more immersion, I prefer blue nights or red/yellow sky when the sun sets... This is realistic, in real life when the sun sets the sky becomes yellow/red and at beautiful nights the sky becomes blue, so in Skyrim it is much better than colorless nights imo. If you want black and white Skyrim world, I hope you will find a mod that works for you. And also you want black and white aurora? or no Aurora at all? You color hating guys should live in different world where everyting is black and white/colorless

Try http://www.skyrimnexus.com/downloads/file.php?id=131, I think it will get rid of the greenish tint that is bothering you so much.
I've been investigating that mod last night. Thanks

Someone made a mod that removes the tint and saturates the color a bit, It's quite nice looking. Check the before/after blacksmith fire pics.

Yes, I like it! Colors are true. For all those who want to see, go to the link provided by Adan above.
Thanks Adan!!
