They used Tyrol Blue for the stripes on the original 69 TA.
After that, they are only matching to a decal, not a paint. The Tyrol might match better, but it also depends on the base coat and similar. And that mix doesn't match what is around 50 years later. Lucerne was an existing, available colour where Tyrol was no longer. Use a decal over white paint, then use it over black, different blues.
If you want a better match, trying matching to the existing decal stripe as that's what they'd need to do anyway with the old codes that no longer translate. A slight variation is likely correct, if yours is enough to bother you, than I'd look into it also.
I can't see the factory doing it that way, more likely a dealer would arrange it if you went back unhappy about the match.
