Cobra Kai said:

It looks to me like Harmy has done his homework and is simply trying to preserve the original colors as they appeared in the theater. From different sources that I have seen, the theatrical version appears to have had somewhat of a warm look anyway, and obviously was much much warmer than the 2004 and later versions. (There's a great reference shot of Leia on Tantive IV over on mverta's site that illustrates the difference between the gout, 2004, and the corrected legacy preservation).

Obviously it won't be 100% accurate until a better reference source becomes available, but I am happy for the most part from looking at the wp.

I don't doubt for one second that Harmy hasn't done his homework Cobra, I just have my doubts about the colour grading accuracy of sources like the saturated GOUT and the Star Wars frames on jedi1.net that have predominantly strong yellow or green fade. Only these few frames from Star Wars look fairly accurate to me (based on flesh tones) Of course, they have issues as well (second too blue, third, fourth, fifth and sixth too green, seventh too yellow), just not as much as the others IMHO:

The first film is meant to be warm, no question, I agree 100%. The question is how warm though. I just think that the yellow is a little too overwhelming in the workprint sometimes, like watching the theatrical release through yellow sunglasses. The scene with Tarkin and his boys having a meeting on the Death Star is one such scene, their flesh tones are so yellow that they all look like they're suffering from yellow fever. Just my two cents. I'll shut up now.
