Capt. Swenson while onboard the USS JUNEAU quite possibly got to see some of these "Pink" destroyers (USS DAVIS, USS JOUETT, and maybe SOMERS) in the South Atlanta when they escorted a convoy to Recife Brazil and back in July 1942. He must have liked the shade.
Really, not much is known and written down about which USN units had this Camo paint applied. Even fewer photos of them seem available (not many photos of the South Atlantic Operations seem to be available in general). Not really sure that the RN and USN versions of the paint are the same formula.
I am pretty sure that the two are not the same formulation, given that the difference between "white" and the ship's hull on the RN ship is less than the difference between "white" and the hull on the USN ship, both said to be in Mountbatten Pink.
Interestingly, both Have Blue and Tacit Blue (The US Testbed Aircraft for the F-117 and B-2) both were painted in a shade like "Mountbatten Pink" which was discovered to be the best stealth paint scheme.
So, that color actually is a very good camouflage paint for concealing ships at a distance (near or just past the horizon, when their superstructure is still visible). The reasons for the Pink being obscured at a distance have to do with how our brains process visual signals from certain hues. It has less to do with us seeing the color as it does our seeing an "edge."
In visual processing tests at UCLA, they showed that people could not discern multiple colors on some screens when they could not also detect an edge between those colors. Mountbatten Pink and the blue-grey night sky happen to be one of those combinations.
But the US military of the 1970s/80s balked at having its most advanced aircraft painted "pink" and instead opted for black/dark grey.
So... They were onto something with the color, but probably had not yet refined it between the two navies' versions of it.
Edit:
But, to return to the Juneau, a contrast study on the Juneau image does not rule out the possibility that it could be a Mountbatten pink. The contrast was not identical to the Mountbatten pink (but then I would need to know all sorts of things about the sun, overcast, humidity, color of the sea, etc. to really rule out Mountbatten Pink), but it was close enough to fall within the range of the two photos given.
