Speaking of the Amtrak Blues, was the Phase I and II (wide stripes) blue the same as Phase III (even stripes) blue? Then of course we could have fading that would lighten the colors.
Believe or not, Wkipedia has a decent article on Amtrak paint schemes:
https://en.wikipedia.org/wiki/Amtrak_paint_schemesBut I'm not sure if I agree with them stating that the platinum mist paint used on the locomotives was gray - I think it was metallic silver (just like the Floquil paint). But I'm no expert so I won't go ahead and change the atricle (unless I find some positive proof).
BTW, wouldn't this thread be a better fit in the Prototype section of this forum (not in N/Z scale)?
