Source of blue tinted paint on underside of '67 Los Camaro floor

[Stillwater Camaro]

I am restoring my '67 LOS Camaro and had to replace the trunk floor and a rear footwell due to rust and old crash damage. In cleaning the rest of the floor, I find it seems to be painted a blue tint color. I'd like to paint the replacement parts to match, rather than paint it all black. Looking for information about this paint and if it is available.
Thanks

LA built cars had more body color painted under rear floor trunk and frame rails then Norwood built cars was your car a shade of blue originally?

No, Gold. On other forums, others have seen this hue on their floors too. I didn't see any mention of this in the research sections.

Can you post pics?  The size limit is 200 KB.  If you can't figure out how to post you can email them to me and I can resize.

I'll see if i can get a clean pic today. I'm under it cleaning the crud off for paint anyway. Difficult to get proper light under there as it's on jack stands.

Actually, I have one from when I put a patch in a few years ago.

Body Pan floor plugs were installed AFTER paint so they would be bare galvanized plated steel and these have paint applied from some owner in its history.

Fact check me boys, Do I have this correct?

So the blue was applied outside of factory building-construction.

I was wondering why someone would paint the underside blue on a gold car, but now I recall seeing blue paint over 2 coats of gold and under2-3 coats of white in some places I stripped, so it may all make sense. Recently sanded all of it off in the cowl... the color does look similar.

I was washing the left frame rail to get ready to scuff and found evidence that the floor was painted by Fischer. I removed the axle bump stop and I believe I am the first person to do that since the day the car was built, and the blue color is under that too. As well as a dusting of Gold overspray. The overspray is heavier on the frame rail, but some must have gotten by. There are runs in the blue in the torque box area that have gold dust on them too. It's even inside the tube for the shackle bushings. Then I scrapped off a small area of the original undercoating and the blue is under there as well.

So the body tag shows Gold?

How does the body tag compare to the VIN?

But you said the blue is on top of gold, right?

[Stillwater Camaro]

No, the gold body color is on top of the blue. Neither tag has been off and the body number is in line with the build week.

Post a picture of your trim tag, please.

[Stillwater Camaro]

Curious what that will show to you.

This pic is from a highly documented, original, untouched Z28 that was certified at MCACN last year. The blue hue on the floor is the same as what I am finding under 50+ years of crud. This Z is Mountain Green and was built at the end of the '67 run and mine was built the 3rd week of Feb.

I am Amazed by the Blue in the inside diameter (Bore) of the Rear spring bushing Mounts-

Wow What is going on here?

Could there Really be a LOT more to this-
