Gameover,
In Europe runway distances are declared in metres so it took me some time to divide feet to make metres; so for the centreline it's 900m in 2 sections - 600m red/white and then 300m all red.
Edge lights only change to amber where there's no centreline - it's called the caution zone. If the airport upgrades to a coded runway centreline then the amber edge can be removed, but many don't.
Again, in Europe, at airports with CAT ll/lll ops and a green and green/yellow twy centreline system blue edge lights are often reduced to difficult curves or edge of apron.
Over the pond our American cousins seem to run blue edge lights down every taxiway leading to the phrase 'sea of blue' - totally over the top imho.
Have a look at the CAA regs in Ch6 of CAP168:
CAP 168: Licensing of Aerodromes | Publications | CAA
Hope this helps
