Con-Cor B&O Passenger car colors

[freeway3]

Is anyone familiar with these models? Made in both 80' & 72' versions, I believe. From the pics I've seen:

The colors seem like 2-tone blue, rather than the blue / grey I'm used to seeing. (I don't have any of these, just going by the pic above & others.)

Are the colors of these cars correct, and if so, to be pulled by what?

Thanks!

The picture looks to be from an Nscale set. I can tell by the Rapido sticking out from the tail end. A 6car set of smoothsides could be pulled by a E or PA unit.
I have no idea if the color is correct or not. ConCor is good for fantasy schemes on some of their cars & equipment. I'd try to see a set before you buy it.
