This one again makes me ask what color are her turrets? I'm sure you are right about all the rest of her, that could easily be Standard Navy Gray #5 though it seems a little dark.
We run into the ever-present problem from period photos--they were taken and printed so as to render the best visual contrast the camera, filme, lighting, and the photographer could manage. Which was further "cranked upon" when the negative was "exposed" to print the photo.
Now, poking an eyball on the Canal photo, a couple of reference items pop out. Those would be the bloomers on the guns and the shade tarp over the forecastle. Those appear to be an unpainted 'raw' canvas, which is going to be a very pale whitish gray.
That gives a place to start comparing the turret color.
This time frame encompasses when "Range Clocks" and "Formation firing" were still common doctrine. So, there is the possibility that the "off side" of the turret have vertical stadia stripes on them in #5 or even Black
This is USS California for reference
Now, if those turrets are a lighter color is ajudgement call, that's a somewhat over-exposed photo.
And, here's USS Mississippi
It's odd that the documentation for the paint scheme is so scanty, as it appears to be pretty common, here's USS New York i nthe Canal
With the distinctly pale turrets.
