OK, here is your answer from "The Man Himself", as I just got off the phone with him:
The first order of NKP Alco Pa units were indeed painted "Nickel" per NKP specifications, with the actual paint being Metallic Silver. This first order was delivered in December 1947. The NKP management quickly discovered that the "Nickel" paint weathered terribly, especially during washing with the caustic soaps of that ear, and subsequently was "deemed un-exceptable".
The second order of Alco PA units (4?), were received in March 1948 and were painted in the new non-metallic "Aluminum Gray" color. The previous order of PA units, and all passenger equipment, were repainted into the new non-metallic "Aluminum Gray" color, which looks like white, but isn't. As additional info, the NKP did not start receiving stainless steel passenger cars until the 1950s.
Doyle McCormack's PA #190 is painted in the correct NKP "Aluminum Gray", and when a paint panel of white is held next to it, the difference can clearly be seen.
