Ciao UFO and all,
NICE choiche ..the Lasagne,..GOOD

The question is not funny,..very cleaver as usual,...

I have never found a reference for a KM office or organization about camouflage schemes, .. even if on a book ' Arnstriche und Tarnanstriche der deutsche Kriegsmarine' there are references and hand made sketches examples surely made during war time I suppose.
Probably my German language limitations,......

On the Italian Navy the designer for warship camouflages was Claudius, and he made all Italian ship camo schemes, I do not know who did it for the German ships.
But surely the German camo schemes were carefullly made, if you think that Adm Hipper for example copyied HMS Liverpool and HMS Revenge camo schemes on 1940-41, so there was some intelligence behind it.
Camouflages started with Graf Spee on 1939,.. and finished with Adm Hipper on Kiel dry dock on 1945.....
Look at Tirpitz camo schemes in Norway with the raising sun on port side,.. and long shadows on the starboard side, ... obviusly made in consideration of the sun position compared to Norway mountains on the background

.
Than all ships on the 1940-41 while on the Baltic sea weared the so called ' Baltic camo scheme ' : Bismarck, Gneisenau, Scharnhorst, Prinz Eugen, Lutzow, etc etc.
So most was depending on the war theatre they were supposed to be.
As far as Graf Zeppelin I think was a bit premature to have a paint scheme already decided before her commissioning, surely they were going to wait some months for the training on usual 2 tone grey's dress,... or a Baltic camo if ready on 1940-41, ... than based on the mission make a camo.
Not much of an help,.... sorry.
Gruss Antonio
