I am pretty sure that von Greim stated to researchers or wrote in his diary, that the stripes and cowling were red and the tail sections of the Jasta aircraft were a silvery white. In one photo he actually colored the struts, cowling, and bands red. So if they are red then the tail is certainly not. Of course JMHO based on other peoples research like Greg Van Wyngarden and others. As for the Jasta 11 Mohnicke bird yes, Fokker Blue/Turquoise works and is generally considered correct, again JMHO.
