The thread on the WT going into the red, and the remark on "cheap paperback bibles" made me think of the old Green NWT.
There was a lot of buzz back then about why it was green. I heard these from various COs -
a) it was Green to prove that it was not from Christendom. Christendom used gloomy black bibles.
b) it was Green to identify us at the door as JWs. We should be proud to be different.
c) it was Green to signify life, like a tree (or a tree snake, I guess). Black bibles signify death (or the Model T, I guess).
d) it was Green because Jehovah blessed his Bethel Plant with a special buy on this green binding material - which lowered the cost of the NWT. Later all the other benefits above were noticed and we gave thanks for the Green. (I can see where this could have actually happened).
This all pretty much went out the window when the Society issued the Deluxe in the dreaded black or blood-like maroon. There was also a pocket edition in dungy brown. I think the Society was reacting to the many witnesses who had their green bibles custom rebound in more tasteful (and less noticeable) colors.
