I’m finding in my project (working with the GOUT, SE and BR) that Hoth tends be be bluer than I would guess. The bright, sunlit areas are very white, but the overcast and shadows are more blue and the inside of the base is very blue. This frame (of the gun exploding) tends to match the Despecialised more than the raw 35 mm, but with a bit more blue.

For instance, there is a triangle of blue sky visible through the smoke and the sky to the left should have some touches of blue. Also the background cloud of smoke to the far right should have a very gray, almost bluish tone. The SE (I’m working on a mix of TB and GKAR) may be crap for DNR and details, but they are a fantastic color source.
