I dug through my collection of topps cards to see what this shot looks like on them. Some may think they’re not reliable color references, but they’re in mint condition so they’re not faded and at least can give somewhat of an idea of the colors, if not a 100% accurate picture. In my mind, they’re useful. Unfortunately, this shot of Artoo and Leia isn’t on any of the ones that I have. However I did notice most of the tatooine shots are pretty neutral. Leaning a little toward yellow but in most shots the sand is almost white. I think the harsh yellows we see on the tech prints are almost certainly a product of technicolor, not so much of the original photography.
