Still don't get the point of why we need this? They can easily set all the T's to a certain color (blue, red, yellow, etc) beginning of the round while they're still in their cells. And your example, just given, in matter of fact mainly why we have "Warden kills only during deathgame, etc except if they are actively rebelling" so other CT's should know the rules and not kill T's and give warnings instead unless they are rebelling in the first place and no need to highlight a T who won a trivia, of which the CT should know that they cannot kill the T who won and not kill the other T's who were chosen by the winner to die since it falls into that certain rule.

/color is a pretty well known command several servers have implemented and I think I might still have binds for from my clan years and years ago. It was restricted to admin use only to help identify teams, etc. But that server also would do things like make a T red after they've attacked a CT (along with the "X attacked Y" message).

But why fix something that isn't broken? I don't see a need for this feature and the headaches it might cause.

I don't think it's necessary either. Some warden is probably going to abuse it on war days. Also since the T would be glowing, wouldn't that make them visible when they're behind a one way wall secret? Considering CS:S still has people's heads go through secrets, people being able to abuse crouch jumping to see through roofs (should be breaking a rule if not already), lots of problems would probably come along with the addition of this type of plugin.

(This is if you're talking actually making them glow a certain color and not just changing their color).

I do realize that if this feature was implemented than it will most likely be abused. There should be certain rules regarding the feature such as wardens can only use it during a minigame that involves T's to compete against each other.
