Harold, I'm not about to argue with Mike Starmer's research, but I'd like to refer you to a comment from Shep Paine. "Over the years more hot air has been generated about correct colours than any other phase of armour modeling." "There are no absolutely correct colours for a particular vehicle.""Aside from concocting your own colours out of thin air, perhaps the biggest mistake you can make is to adhere fanatically to colours from photos, drawings, or even colour chips."
My motto is if it looks right, it usually is. Weathering, colour variations in photos, or print, always affect the reference. And then the vehicle is going to be seen under a film of dust and/or grime.
