What's the best engine paint for the red that's on the early slant 6s and 273s?

Well, I'm pretty sure the paint on my 67 273 had become more orange and less intense over time, from repeated heat cycling and age... judging from the color of the Commando decal on the air cleaner, and the red paint on the Commando badge, at any rate.

I wound up using the International Harvester Red as someone had recommended. I would agree it is a shade too "cherry" red, however. It's too bad there aren't factory paint cards for the engine colors — or are there? I have never heard of one.
