I’m so glad you have decided to make a preservation of this version of Fellowship. Like many people I was disappointed with the green tint in the original blu-ray version. I used the You_Too AVIsynth GIMP re-colour script to remove the green tint from my version.
I did anticipate the 4k UHD release, but was annoyed that they should so drastically mess with the original colours, especially when Elrond has his flashback to Mount Doom, it does not appear as if he is standing near molten lava, because most of the orange has been removed. This seems like a mistake.
The colours in your screenshot look great. Very much looking forward to seeing it in motion.
I already have the 3 other main colour preservations, KK650, Dwalin, 44rh1n, and have been looking forward to this version since the first post.
