Been sloshing some paint on. Not without it's difficulties.
During and after WW2, the Admiralty saw fit to dump lots of information, in particular, information on Admiralty paint(s).
If you really want to know more about this, you can visit the Sovereign hobbies website. James Duff(Jaimie) has done a lot of research on the subject and published his results. It's available to download, free, as a service to modellers. I comes as a PDF file, about 11 pages long, it's a magnificent effort and shows some of the problems ship modellers have when building RN ships of that era.
After some effort, I ended up with three painting diagrams, all slightly different in both the pattern and colour call up.
So what you see is what I think the ship may have looked like in late 1941.
Decks were a bit of a problem, Trumpeter would have you paint them a dark grey (extra dark sea grey).The information I found was a little confusing. One school of thought says steel decks were painted dark grey, maybe dark grey blue. The wood decks may have been painted camouflage colours but the pattern is largely unknown. Another school said all ships should have their decks stained with black stain, not paint.This had the effect of darkening the decks but still leaving the caulked seams visible. Finally, Trumpeter have depicted the fore-deck as planked, I've found a very clear picture showing it was steel, painted a dark deck colour so the fore-deck planks needed to be removed.
I've gone for my version of the pattern and colours, steel fore-deck and wood decks stained, probably not dark enough but who is to know.
