YES, I knew that, it is a very beautiful city, I want to come back one day.
Now on the J camo scheme 2 tone grey, RAL 700 and 7001, and red turret tops but also bow and stern with a darker grey, later removed when she was torpedoed, there is a clear photo showing Gneisenau in Trondheim with that scheme on her.
This scheme shortening the hull ( both bow and stern ) with a darker grey was later used on Tirpitz, Prinz Eugen and Admiral Scheer as well during an Operation called Sportpalast on Febraury 1942.
Gneisenau had it on her first, on 1940 ( see a photo on my plan of 1940 under the month of May ).
In fact your colour photo with the lighthouse shows Gneisenau just torpedoed with a big hole in the bow, with some dark area on the bow under the forward turrets ( probable torpedo explosion effect ) but without the J camo scheme, that was applyied, and later removed.
Yes, the island I was referring is exactly the one you are talking about my friend, good to know more, thanks .. I love history,...
I can fill up you e-mail reader with Gneisenau stuffs, as I was ready to post her story exactly as I did for Scharnhorst.
If you want I can send you all her drawings and camo schemes, lots of photos and more,..including a very nice invented camo-drawing done in cooperation with a young good boy, named Vlad
, ... that shows her,... after a potential refit on 1946 
.Keep in touch separately
