This is a colour we directly matched from a screen-used ANH Death Star Tile. The 2 primary colours used have been added to our colour inventory. It appears that most of the tiles made by ILM were covered in the primer as their main colour, a light Grey. AX-033 ILM DS Surface Grey 30ml Acrylic Paint makes for a great colour when building Death Star tile bases for your models. As we believe it was a primer its use across the Star Wars films is highly likely and also the colour we choose for base coating Slave 1 before the Weyerhaeuser Green and Dark Grime Layers are added.
Best described as somewhere between White and Grey in appearance and a true ILM known hue/colour
