Dr Color Chip, useful for old paint codes? Options

[1970 Neun vierzehn]

I have used " Dr. Color Chip" to touch up some very minor chips on my 2011 Audi A4. The touch-up was a perfect paint match, so much better than the factory touch up paint that can be purchased at the dealer. The Audi paint was so bad that I threw the touch up pens away.

But, does anyone have feedback if "Dr. Color Chip" can match 40+ year old paint codes? Their web site displays the paint code for my '70/4 (L11E), so I suppose they can formulate the mix. Although the car was painted its' original color eight years past and has been extremely pampered, I still wonder if the color formula can be produced to a perfect match. Unfortunately, after eight years, I finally got my first paint chip, on the rear deck lid no less.
