What is the absolutely correct blue engine paint color for a 74 Duster?

Tanker said
This is mine. I can’t swear that it’s correct. It was custom matched to cleaned up original paint that survived on one of the valve covers, but more than forty years of exposure to oil, grease, dirt and ultra violet light may very well have altered that sample. Anyways, it was the best I could do.View attachment 1715940343

This right here is the closest if not right on it in this whole thread. All the rest are "too blue". Chrysler corporate blue just ain't "THAT" blue.
