If I recall the painting instructions to the fleet, all auxiliary craft were painted ocean gray (5-O). This seems consistent with the color photograph you have posted. I can dig out the documentation if you would like a definitive citation.
No I have the painting guide for the ABSD-1 Which lists the Ocean gray as part of the standard paint scheme. However The pictures I am showing are not the standard paint scheme. The only section of ABSD-2 that is in the standard scheme is section D (4th from the bottom in the top picture, 4th from right in second). My interest is in the dark paint, both interior walls and exterior. The light gray on the outside is most likely 5-P Pale gray or 5-L Light Gray, based on other color photos of other ABSDs I have found.
For example:

What I can't find are any other original color photos of any ABSD with as dark of paint as ABSD-2. Even in black and white photos it is unique.
Based on the 2 color videos of ABSD-1 on Youtube the deck on the tops of the wall on the walkways are like a red oxide primer color, even some evidence of red oxide on the exterior walls where the topcoat is coming off. The top of the decks on the floats (work area) appear to me to be in a natural metal, and surface rust abounds on all often submerged flat surfaces, as seen also on 3rd photo above also. It is possible that is just very dirty red oxide on the deck as well.

So with the colors I think I am confident in or pretty close to, what is the really dark color on those walls? There is a distinct demarcation line in the 2nd photo on the interior wall as well on the 4-5 sections at the top right of the dock. The top color could definitely be 5-O but the darker color is still a mystery. If it was a red oxide wouldn't it be similar shade as the hull tops or walkways? Is it possible its Dark Sea blue or maybe even black? Looking at the freighter in picture 2 it looks like a good tonal match.
Open to ideas here anyone.
Thanks
