That clears it up better. I do understand their name 'field grey' isn't correct, it's more of a greenish color. I'm just going off the paint instructions from the kit and what making me ask questions is their grey is light, and I didn't know if the germans switched the grey colors from the early 30's to the 40's or if it's always been a german grey. So from what you said Jamie, they've always used the German grey and Trumpeter should of listed it as that, not field gray and that their color may be too light?
Don't worry about the blue tint, I have no desire to go that route. If I can find enough references and matching colors in the Testors selection I may try the Feuersicherlich Buntfarbenanstrich tricolor scheme, I just need to do more research and searching around. I have no reference books so all I have is the internet.
