If you want to have the output also formatted when issuing the /say or /msg commands, you'll have to script custom aliases.
Code:
alias say .msg $active $$1- | echo -artc own $+(<<,$me,>>) $1- 
[color:red][/color]
alias msg {
  .msg $1 $$2-
  if ($show) {
    if ($window($1)) echo -trc own $1 $+(<<,$me,>>) $2-
    if ($query($1)) echo -ts -> $+(*,$1,*) $2-
  }
}

Note these are just examples...
