Well, if the colors are still in use today, you don't need to match. All paint
contains
chemical pigments that give it a particualar color. These pigments are effected
by
their exposure to hydrogen, nitrogen and oxygen in various ways. Many color
charts
will rate a color for hue, value, etc. AND permanence, meaning how stable the
color is. I wish I could remember who published the article about the Garber,
but
it went into some detail about the pitfalls of paint matching.

Where do you get these chips? Does the German government maintain this system?

Several caveats here. If the paint chip is new within the last few years, it's
accurate. If not, it is questionable. A contact who works for a local
engineering
firm told me that they throw out their chip book every three years and get new
ones.
The reason is the same problem with the paint themselves, they begin to change
over time. Colors in any book printed prior to the use of computer color
matching
are printed in inks that are hand mixed by the printer, and are not standard by
any
means. My father was a printer, and I watched him do it. In most cases it is hit
and
miss, and rarely the exact correct color. Two printings of the same book will
often show different colors.
