Also of course if you get it wrong the cb will ping and there are not that

Er! The cables look like nothing I have seen in a 2 Way switch
arrangement.

But they look like 50% of the thousands of two way switches I have seen.

RGB?


Ones exposure to domestic wiring is a trifle limited, but I have not
come across those colours in a home before.

Whatever the colour, cables do not just "drop out".



RYB.

I did not watch them on TV.

I stand corrected. Apologies, although I must admit I saw the insides
of a lot more TV sets than light switches :-)

What happens if the phases are switched, does the room go darker in
the daytime?


It's single phase. There is no phase to switch/short circuit to.
