In my text-events a Channel Action's nick is painted yellow, and Channel Action Hilight is completely red. It is my preference, I did it, but I am not talking about it.
What bothers me, is that Xchat alternates between "Channel Action" and "Channel Action Hilight" when displaying action messages in the channel. One user's action appears in yellow, and the next moment the other user's action in the same channel appears in red.
At first I thought channels' operator's and voiced people actions are painted red (ie. displayed as "Channel Action Hilight"). But it is not the case; there is a channop whose action messages are painted yellow as well (displayed as "Channel Action").
Please can someone explain why Xchat decides to display actions alternating between CA and CAH ? Or, how Xchat differentiates between CA or CAH ? All people I asked what exactly did they do to produce their action messages (red and yellow), replied they use a standard /me without doing anything special on their side.
