Hello, Thomas,
In Australia, paint matching can be done by taking a small sample to a specialist house paint store, or a car-painting/repairer outlet, both of which scan the sample, then produce a report on the colour.
Don't know if you have these facilities in Denmark, but if so, you might consider it.
You might also visit this site:
boardlady.com/ to see if she has comments about the types of paint to use.
Agree with your comments re F2.
Hope this helps.
