Starting to probe this lume thing more. Honestly, I never thought that much about lume until recently. With vintage watches, you kind of just accept the fact that the lume, if original, will be in various states of distress: discolored, flaking, peeling, or just plain missing. Jeff and Rich have weighed in on Monacos, the consensus seeming to be that they left the factors with a green/yellow that in the best cases has patinaed to a cream color. Eyeballing some photos of Monaco reissues, it looks like they are now leaving the factory with bright white shoes.

That leaves the question of other models:

Touring around the "Bible," we see:

p. 214 it seems the Montreal Blue had a bright white
p. 218 Montreal PVD green/yellow
p.116-118 Carreras true white?
p.99 Camaro also a true white
p. 67 Autavia true white (look like service hands, but is watch NOS?)
p. 69 Autavia classic cream
p. 71 Autavia lime green with ???? inside
p. 37 Autavia true white (relumed?)
p.146 Carrera faded white (seems like it might have been true white out the door)
p. 234 Silverstone true white

So it seems that the factory specs ran the gamut from bright white to a less-bright white to a green/yellow. I am really curious now whether there was intra-model and intra-year variation for lume; was this another decision that was made on-the-fly and dependent on materials at hand?
