True. And this was brought up a long time ago as well. I still think that notices really should use the notice color instead of your "own text" color. There is a valid reason for both options, though. It really depends on a person's preference. I rarely use notices, so it doesn't really bother me, but I see no reason why it should function differently than actions. If /me doesn't use "own text", then why should "/notice"? They're both text that you are sending.

Anyhow, for those who want it to be the notice color, it isn't too hard to script that and make it use the notice color instead. I think it should be built-in that way, but at least you do have an option.
