Paint is something that needs forethought. Not all primers are compatible with the paint. I use Dupont/Nason single stage because it is common to my area, and I feel is better than a 2 stage base coat top coat. The red I use from Nason 9066 IB ,says on the can it is Volvo Red, so don't let the discriptions fool you.
That said please keep in mind IH bought paint from the lowest bidder and paint colors varied over the years.
Have fun, that is the most important thing.
