Some of the comments in that initial post by the Eaglemoss guy suggested something in between. I suggested they use the dark grey color from the bottom one as it, but then use the darker purple color from the top model where the lighter, shiner grey is on the bottom model, thus giving the illusion that the ship was purple. Because like you said, the difference between shooting models and on-screen lighting, varies so much, it would be almost a guess as to what would be accurate on these real-life solid die-cast models. That said, out of thew two pictured here, I would prefer the bottom one, but it really needs to be a mixture of the two. A few more purple highlights to the bottom one would make all the difference, I believe.
