Orders were issued towards the end of Dec. '44 to switch from Dunklegelb to Olivegrun, but it’s debatable if it ever was implemented before the end of the war as stocks of Dunklegelb had to be used up first. However, it does appear in some photos that, at least, some components, but not the entire tank, were painted in Olivegrun.
In response to outlined spots camo jobs, I would suggest that if a vehicle had the spots outlined first by brush, then infilled by spray gun (with the same color), the brushed outline would appear darker (because it is applied thicker and more opaque) than the infill. In B/W photos the outline and infill could appear as different colors. …Just a theory!
