F-Unit colors

["gfandwrr" <gfandwrr@y...>]

The F-units that are coming on, or have been on the market, seem to 
be painted white. I was under the impression that passenger 
locomotives were painted silver, or was that just E-units? If 
the "F's" were white, which are approprite for passenger service? 
Unfortunately the books I have aren't much help. Illumination please!
