Look at the Rivendell Council one, again the left is way too orange, from the tress that should be green, to everyone's hair colour. Now look at the right one, much better skin tones, hair that is more blond for Legolas and brown for Borimir and the back of the head of Aragorn.)
The filters in the film weren't supposed to look "realistic." They were used to help convey the fantasy nature of the setting. Of course no one really glows orange like they did in Rivendell. Likewise with the blue/grey filters used in Moria, Osgiliath, etc. But that was never the point.
Like I said before as long as he preserves the integrity of the theatrical editions (unlike some other director) I don't really have a problem with it. The fact that the green filter was added to FOTR:EE and not TTT:EE or ROTK:EE highlights the notion that its most likely an error and not something to be celebrated.
