I would disagree vynsane. Every time LEGO releases a set of a starship of vehicle that is all or mostly grey, they tend to botch it by adding a lot of darker/lighter shades of grey (or less recently, tan), which leaves a set looking quite unlike its movie counterpart, color-wise. I think even the 7657 AT-ST or the 7663 Sith Infiltrator (or the 7778 Midi-scale Millennium Falcon
) would have looked much better if their hulls were the color they were supposed to be.
I believe cas is correct about the actual studio models being white:http://www.theforce.net/swtc/Pix/Xbarbican/eydc5/5r14isd.jpg
The photo is from theforce.net and is supposedly the model of the Devastator
that was used in the film. It's clearly white. However, it obviously looks more grey in the film.
As for the set itself, I'm not so sure whether I'll be picking it up - the accuracy of the model (proportions and whatnot) are stil debatable from that one shot. And after all, it wasn't until I actually bought 7778 that I noticed how horribly off the proportions were. (For one, those mandibles are obscenely large.)
