Alpina Blue...

[Masskrug]

...is sweet. Looking at the B7 in the Roundel. Me like. Wish I could see the color in the flesh. It's their own 'special paint', ya?

Yup, special paint. Actually, there is another name for it call 'Dunkelsaphirblau'. I have not seen it in person, unless you consider a bottle of the paint itself. Very close to Topaz Blue with a couple of shades darker.
