Paul,
I had the same thought. I looked again at the photos on the listing, and the shot of the data plate shows signs of overspray and/or poor masking with green on the plate itself. This shade of green (avocado) wasn't introduced to the industry until 1966 and at that time it was a shaded color, with darker edges. The solid color version didn't appear until 1977. I believe even the 1966 date is later than one would associate with the photo and condition of the owner's manual, included with the appliance. If Ironrite offered a green at the same time as the pink one referenced, it would have probably been a more-minty green than avocado green. This one could have left the factory as a green one, with the cabinet updated later with a new coat of paint, I suppose.
