I don't know much about this stuff, but I have one four-stripe PA in the fleet. I bought Grande Gold in Scale Coat, and discovered it to be identical to Daylight Orange.
While I am at it, I also found that Daylight red is a match for the ATSF red that is used on the warbonnet PA, at least in Scalecoat's estimation, which is good enough for me.
Stunning passenger train . . .
