When I first saw the 2012 Blu ray, I thought to myself, “Finally, this movie looks like I remember!” It’s warm and friendly looking again. Just my 2 cents, but the (2012) blu ray version looks closest to what I remember seeing in theaters. Now I’ll grant you, the cave shots may be a bit brighter, and some scenes look blurry (the spiders on their backs), so maybe not perfect, but good.
I have seen a 35mm print at a local theater and I partially agree. Very yellow-leaning, but not necessarily warm. RotLA 35mm LPP looks nearly exactly like the print I saw color-wise. However, I feel like the Blu-ray very much leans too red/warm at a lot of points. The print I saw was closer to the 4K during specific dark scenes like when Belloq drinks wine with Marion. You can see that reflected in LPP as well. I lean closer to the 4K for that reason, although the Blu-ray has a lot of merits. To me, natural looking colors technically look closer to the 35mm print I saw than the warmer colors on the Blu-ray.
