Engine paint decision and questions

So I know the engine paint question has been beat to death but couldn’t find the answer to my exact question. I was going to buy rustoleum IH red farm implement paint but it looked really dark. Someone mentioned that the new stuff is way off from the old IH shade of red? Is that true? It’s bad to ask but...is the Ford red closer? Seemed brighter? Just don’t want someone to walk up and say “hey your engine is painted ford red, what the heck”? Or I will paint the engine hemi orange? It’s going in a 1965 barracuda with exterior color kk1 peacock blue (medium turquoise). Thanks for the help.
