Inspection marks were not body paint. You can go to an art store like Hobby Lobby they have 100s of colors in small size containers.
I thought MMC says some of the inspection daubs are very close to body colors. Isn't that a good place to start if you are just eyeing little bottles of paints at Hobby Lobby? Like there is a Testors Sassy Grass that would match the bright green. Otherwise, if you're not buying a kit from Frank Badalson for your plant location, everyone doing their 90-point restoration inspection marks will all have different hues.
