on ^[color:Red]$:PART:#: {[/color] - the $ doesn't work with ON Part, only with ON Text and the likes.. $ means to look for a regex match, so it will not work there.
on 1:QUIT:[color:red]#: {[/color] - in the ON Quit event there is no channel, since you quit IRC and not a chan. If you would like to get the channel, I suggest a while loop using $comchan($nick,N).
I didn't understand what you wanted with the ini file, sorry
