yes, I located several entries in the different books that I have about the do 217 and that is that the plane had two decorations, the first was the prototype 07 of the plane series in two gray tones rlm75 for the upper part and rlm76 for the rest and then The camouflage that they have placed when the plane was already in production is made.
"Dornier Do 217 N-1. Prototype No. 7, GG + YG (radio codes) Rechin, Germany, Summer 1942. Finished in RLM 76 Light Blue lower surfaces and RLM 75 Grey Violet on the upper surfaces with high fuselage demarcation. In the summer of 1943 he appears in the photo you like with the chipped and mottled pattern on of RLM 75 Grey Violet and RLM 74 Grey Green, but wartime photos look more like a single RLM 75."
I have not found on the net images of the books that I have so the copyright is involved and I will not put them
