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

I had a shiny painted engine a few times..... then it got some gas spilled on it, some oil and then dust got on the oil, hood up and got some bird poop on it, but it was impressive for a while!!!
I had a bud that bult him a 70 Cuda 440-6 clone before they called them clones. He had bought a big fancy house for him and the wife retired to play with his cars. One day while "tuning" those triple carbs, it caught fire an burned down the house. He AND the wife was PISSED!!!! and this guy built and raced hemis and MW starting back in the 60s!!! Go figure!!??:BangHead::BangHead::BangHead::steering::thumbsup:
