Let's take a look at what we are aiming for and you can take it for what it's worth.
Like all of the combatants during the Second World War, camouflage and protection was the two main requirements of the paint used and by the time this point in history, everyone had at least 30 years experience.
The FS color chips are used as standard for 'me' to tell 'you' what the color looked like.
You could use the color chips from the Wally World/Benjamin Moore, but not everyone has access to those.
There are others. RAL, ANA, BS, just to name a few. I don't think FS is picked because of color selection.
Have you ever pursued the RAL catalog?
Hang on to your hats.
Japan, had a set of lacquered tiles with about 40-50 colors on it. The paints that the paint manufacturers made for IJN and the IJA used this as the standard.
Sit down, this is where gets good.
Japan did everything in its power to destroy as much record keeping as possible when the war was known to be lost by some.
There are three left known to exist.
One set was seen as recently as 20 years ago and examined by David Pluth of J-Aircraft site.
I believe he was allowed to bring in comparison samples to evaluate what was there.
Another set has not the light of day in 40 or more years and is part of a family heritage collection and may not exist now.
Big question mark, right?
The third missing set, is even more elusive.
None are for sale.
Anyway, sounds like the legend of Whooley Swamp or some campfire story of Robert Johnson.
Let me offer this as part of the internet rabbit hole I've been in.
If you'd like to take your own journey down the hole, can suggest Dave's site above, or a extreme favorite of mine Nicholas Millman's

My thing is colors.
I have more stalled projects, sitting around waiting for the elusive color to fall in my lap.
Don't work that way.
I am very far from being an expert and I have stated before, close is good enough.
