@BuddhaMaster: Hmm, where to begin. Firstly, I'm not reverting the blu-ray back to the Special Edition, by which I assume you mean the '97 SE release, my Semi-Specialised releases have never officially existed because I have removed/changed awful scenes that were in the original '97 SE like Jabba the clown in Star Wars, Greedo shooting first and Jedi Rocks. With these Semi-Specialised Editions I have kept all the changes I considered improvements, like the improved x-wing special effects during the Battle of Yavin and the Luke and Biggs scene just before the battle, closing his character arc started when luke first mentions him at the start of the film and also to add greater pathos and sense of sacrifice and loss to the Battle of Yavin.
As for as the colours are concerned, poita very kindly helped me get a feel for how Star Wars looked on the theatrical prints, I then had a look at Althor's COLD edition of Star Wars to get an idea of some of the different colour palettes that the film has had. All of them have problems, the fleshtones of the GOUT are far too red, the '97 SE laserdisc is underexposed and has a strong blanket blue tint throughout the film that is very unappealing IMHO and the 2004 DVD has all the colour problems we're already very familiar with. The japanese special edition laserdisc has the best colour palette of the bunch with the most appealing fleshtones IMHO but is over-saturated and has a strong blanket orange tint throughout the whole film so not all that reliable colourwise.
Basically all four home releases have numerous problems with their colours/image dynamics so I couldn't use any of them as a colour reference, so I regraded these films using just the fleshtones and lightsources as a guide of what the colours should be, removing the blanket blue tint on the blu-ray in the process. I was not trying to recreate the colour palette of any of the home releases, especially the '97 SE with its underexposure and strong blue tint, I wanted just to get the colours and fleshtones as natural and balanced as possible. That's probably what you find appealing about the colours of my Semi-Specialised Star Wars V2 release.
