I'm puzzled too Colo, even by looking at actual photographs
This picture of USS Kidd taken in 1988
shows a blue-ish Haze gray, closer to the upper two drawings. On the other hand this one featuring the same ship in 2004
shows a more standard grey paint scheme on the upper-works instead (yet, she might have been repainted in the meantime, possibly?)
This B&W picture of USS Mobile in 1943
shows a distinctive stark contrast between the two paint shades, closer to the one represented by your third drawing.
Pics (1) (2)
of BB-60 Alabama also shows a similar stark contrast between the Hull and superstructure. The same goes for Missouri
It is definitely difficult to guess it correctly, Looking at pictures has actually worsened my confusion instead of clearing some doubts.
Aestetically speaking I'd say that the middle drawing looks like a good compromise. The standard Grey one looks good too, but we're all used to see that colour cohexisting with the Measure22 hull. As for the standard Haze Gray, while I still got the feeling of being too dak, the more I look at it, the less it looks wrong, although not enough if compared to the two other shades.
Hope this was not just a futile stream of consciousness.
