See urxvt(7) for all command sequences.

No, I mean, swap the colours, not the indices. You can do this easily
from a shellscript by using the OSC 10/11 sequences for example (look for
"XTerm Operating System Commands").

Yes, this makes it very clear.

Hint: if you want to make the plug-in portable, don't use the windows
process emulation code (so called "threads" in perl, even though they have
nothing to do with threads) - it makes no sense to use it under unix, and
is often disabled because of the very large overhead it causes.

And last not least, keep in mind that urxvt does not support the windows
process emulation code, so you have to fix the race conditions that ensue
somehow (e.g. by not calling urxvt functions from any other "thread" than
the urxvt one).
