Why Only One Color for the Station Wagon?

[jimalabam]

Very interesting re. the Blue Station Wagon designated for the U.S. Postal Service. Many years ago, I heard of such a 1931 Wagon, BUT have never found any verification ANYWHERE. FMCs answer was Model A Station Wagons were only painted one color, MANILA BROWN. Until someone disproves and verifies a dispute of Ford's answer, I being the purist I am, will agree with the Ford answer until then. Jim Langley...

Why would they have been painted blue for the PO when the mail trucks
were olive drab.
