This is from a heavily red-faded print and the colors have been partially corrected but trust me, I've seen what the print actually looks like and you just can't use it as a color reference, because half the color information is missing - this is why Hoth looks whiter here - most of the blue channel information is gone from the print.
Combine this with the fact that poita has seen a reference print that isnt faded (iirc) and I'm willing to believe him over this any day.
