It's the same colour as the actual material so an aluminum, silver steel type of colour and some parts are rusty, mainly from the back, some paint is fractionally on parts of the ANH mesh additionally but it's not very consistent. And it's not brand new stuff, so shiny is wrong.
As someone mentioned above I have seen many people tone the mesh colour down by either painting it a dark grey, dark steel or Gunmetal.
Just stay away from too shiny, all black is not accurate :thumbsup
