I remember a report elsewhere, probably on
Kartonbau.de - Alles rund um Papiermodelle, Kartonmodellbau und Bastelbogen, where the superstructure was not colored the correct way, which was grey. Instead of that, it appeared rather somewhat of a light green.
And the underwater part of the hull must be green, not red. I do not remember how the paper model I talked about was.
