Can you tell the vintage of a lens by the shutter color?

Friends, I am lens shopping and notice that some lenses have diffent color shutters. For example, some Fujinon 90mm's I have see sometimes have a black shutters and others have this scalloped metal finish. My only lens at this time is a new Rodenstock that has the black finish, and so I was wondering if lenses with this shutter color are likely to be newer versions than other lenses with the silver finish.

In many cases the newer lenses have black shutters. But there are some other things to consider. This is a good resource for Fujinnon lenses:
