Paint Color Opinions?

Sorry about my old stiff fingers and no proof reading. Like he said, bc/cc is base coat clear coat. Some call it two stage.
I still say B3 is a silvery blue, yes lighter than B5. Like someone said B5 is not exactly the exact same year to year maybe.
As the story goes, Petty came up with Petty Blue some say, by mixing a can of some sort of Ford blue and white.
