They are typically the same as regular Mustang given the same engine application . Air or no air would be different markings because they would be different springs.

Good place to start is what body style, trans, AC or no AC we know PS, engine size and date for this example
If you respond back we can quickly provide the right information ;)
My '69 GT500 sportsroof, 4-speed, no a/c, built 06/06/69, had pink and gold stripes on the front springs. FWIW.
car is A/C and P/S with A/T

So a 428CJ auto, AC - PS and guessing fastback finished at Dearborn 6/13
Looking at buildsheets from other examples from around the same time period with the same specifications i looks like the front springs likely been marked with 1 Gold and 1 Gray stripe
If enough paint was applied with the runs can appear to run upward once the spring is installed as it appears that they were striped (at least the results of) sitting on the flat end of the spring
Hope this helps
you da man Jeff. thanks
Seems to match the chart...bodystyle is also a factor.
What's that they say about leading a horse to water?

Pretty certain the majority of them were like the rear springs and just oil quenched heat treated metal. Color would vary depending on how fresh or old the oil was. Of course the finished look would look similar to other finishes from a distance. Guy that laid out San Jose described them as "phosphated coil springs" thirty years ago while he was redrawing the plant layout. When question - he stated he could not be certain - but that is what they looked like to him at the time.
Later NOS and service ones were painted black (like rear springs) so that they would not surface rust while waiting and sitting on shelves at the dealerships
Haven't taken the time to figure out and test a solution that would test and confirm phosphate coating on steel parts but would like to find time to do this
I would think testing coils with a solvent to see if paint comes off unsrestored coils (not dramatic rusted ones) to eliminate paint from the possible coatings would be helpful in determining if some coils (non service) were painted also or none were.

have done that over 20 times so far. Not bubbling or lifting of the finish as you would expect with paint. On the rougher ones you can chip off the finish as you can on some crustier (likely from using dirty/contaminated oil for quenching) examples and the coating will flake off on those and at times will react to a magnet
Im not that smart Ed 🤔

Get on the bus and go to class. ;)
This is an NOS Gold / Gray coil that was for sale on eBay last year. The dark color is not paint. It is the result of heat treatment. Notice the hurried / sloppy way the paint is applied. It's good enough for the purpose.

LOL looks like the parking lot next to Roush's shop. And that guy in the window of the short bus kinda looks like Ed.
