It's pretty, but if there is no blue in the second picture, I have other problems. As a commercial print shop owner, I am very well aware of mixing all shades of gray and you should never see anything but black and white in any shade of gray.
In the engine photos back from the day, the black distributor cap is very telling. The color they used is right in between black and medium gray. But its like someone else said earlier, they didn't have controls on that color that were all that meaningful because I have seen stock engines in various different shades. It reminds me of the very same dilemma we have with interior colors.
Be happy with your choice and move on I guess. For our original poster, you can get pints, quarts and aerosol from The Filling Station if you like dark blue-gray, or a little milder gray-gray from Bill Hirsch in pints, quarts, and aerosol. That is what I would take away from this. The idea in the first place was a machinist gray I am sure.
All of the engines here are painted with Bill Hirsch...
