I like the looks of the Filling Station paint color. Its fairly dark.
I have seen two original engines with enough paint left on them to see the color. It was dark. Darker than the Filling Station paint.
You will know that you have it right when you develop oily road grime on the engine. That grime is close to an exact match to the original color. No hint of blue hue that I could see.
Interestingly enough, I recently help a guy clean up the engine on an original in every way 55.2 235. When we wiped off the oily road grime, it was not a match for the underlying paint.The 55.2 235 paint was lighter in color. (This engine still had the original painted on yellow script on it.) You could have talked me into saying that the engine paint had a very slight hint of blue in the mix.
