I\'m thinking the lighter grey (since the backpacks are darker than the armor plates) is either a mix or a base from their new foundation paints. If it is a blend I\'d have to agree with Uberdark as to it\'s consistency. The backpacks look to be basecoated in straight Shadow Grey.
GW only has 2 oranges I know of. I\'d have to say the markings are in Fire Orange.
Hope I got the color names right, I\'m looking at my Vallejo paints and trying to remember the names of the GW equivalents. :drunk:
