My bad! I misquoted about the primer. But my question/statement still stands. To me it sounds ambiguous that half the surface remained red primer, and the other half, a camo color. But I assume it means over the red primed surface, half the surface was one color, and the other half was covered by one of the other two colors; no overall base camo color.

Like I said in my earlier post, the red primer was fully covered by all three colors together, but not on top of each other from september 44.

Before september 44 the red primer was fully covered by dark yellow, on to which brown and green patches were then applied. So the yellow underneath the brown or green was considered a waste of paint.

The article had a translation error of the german word "sparsam" (sparingly, or without waste).
