Bob, in person in may seem a hair bit darker but I think that picture is representative-that is 25+ yr old Bill Hirsch paint and 50+ yr old Ford paint. It is pretty close. I always thought my factory paint batch is a little darker then typical. BTW that manifold is aluminum.

IMO from personal experience painting bare aluminum vs bare steel will yield a lighter shade for certain, which may explain the difference we are seeing. I used primer on all my engine parts as a baseline. However, here was a noticeable difference also on my unpainted bell housing as I couldn't to primer it.

The Bill Hirsh paint may be good however it is typically a different darker shade not in the range of the factory paint . It is easy to tell as the wrong shade on the show field.

Has been my experience also. There is another supplier (sorry don't recall the brand) that I see from time to time that has a little purple cast to it, when the sun hits the surface, that makes it unacceptable IMHO

I am guessing you are thinking about the POR 15 engine paint .

This one has a bit of a purple tinge to it imo
