Mmmh I can say, watching it now inside the box, that it's a cool grey with a kind of metallic shine... it's not easy for me to explain perfectly (damn english   LOL) so I'll try to make a good shot now to this grey plastic  

edit: I hope this shot can help you to understand.... anyway, judging this beauty live, it's really a great great figure  

 

I got mine last night and really like the color palette, despite being slightly disappointed with the dull grey used.
