So why are we trying to remove the green tint from The Hobbit now that we know it's supposed to be there?

FotR I can understand, but if the filmmakers intentionally set up their current film(s) to have a specific color timing...

I suppose some people like their skies blue and their clouds white, like they were in the original lotr trilogy before the remastered fotr ee blu-ray came out.

If this specific colour scheme was only in one scene, that'd be perfectly fine, in the fotr ee dvd colour grading is used differently all the time in different scenes to create a certain distinctive feeling. It is the fact that this green tint has been plastered across the whole film irrespective of scene that bugs people the most.
