I noticed something with the color correction, in a few of the videos that were posted. I don't know if these were intended to be the final shots or if they have been corrected.
The hue of the Snowspeeder pilots costumes is not consistent between every shot. Some times, the costume is much too red. The real flight suit (pants) had a mid-orange hue with no shift towards red. The jacket should have largely the same orange hue as the pants (coveralls) but be only slightly less saturated, except on Dagobah where the jacket gets darker because it gets wet and dirty. If the jacket has a shift from orange, it is towards yellow.
See especially in the shot where Han arrives at Echo base after leaving Luke. Look first at the pilot that passes Han Solo and then at the pilots working on a snowspeeder. I noticed no such color problems in my OOT / laserdisc-RIP.
The past few weeks I have been studying all the images that I could find of the Hoth Snowspeeder outfit, because I want to construct this costume for myself. I have looked at both movie stills, production photos and publicity shots. When I have come far enough, I will of course make my patterns and other findings freely available for everyone else. Doing research on costumes and props sometimes makes you overly attentive to certain details...
