Nice photo's you have added there from Germany.
Interesting to see that on the domestic switchboard photo, that the new "harmonised" colours have been adopted for the phases.
Black, Grey, Brown (Phases) and Blue for Neutral.
In The Netherlands (where I originally come from) we used Brown for all three phases or Brown, Black, Black with white dots. (Pre 1988)
These new colours were adopted in the UK about 3 years ago
