Google is sweet lol)What is that
Feldgrau (field grey) was the color of the field uniform of the German Army from late 1907 until 1945, and of some post-war uniforms of the West German Bundeswehr and the East German NVA armies.[25] Metaphorically, Feldgrau used to refer to the armies of Germany (the Imperial German Army and the Heer [army] component of the Reichswehr and the Wehrmacht).
The word feldgrau means "field grey", and by World War I the color was a light grey-green, though there is no specific color, rather a color range of greys to browns, that was one of the first standardized uniforms suitable to the age of smokeless gun powder. Formerly, the Germans wore a Prussian blue shade similar to that of the French.
Sweden used a very similar color for infantry uniforms, for example the grey m/1923 and later on grey-green as the German ones. The last uniform to use the color was the woollen m/58 winter uniform.
D'oh . . . why didn't I think of that?
