I understand what you are saying, I should explain I run a radio station and the chat room is fast, I mean really fast, you can make the bot give shout outs to the DJ and text moves up very quick.
Hence the need for using colors to watch out for certain people.

Like I said I don't use them in normal rooms I try and turn them off, it's just a pity that people have such a bad attitude towards this.
There are so many idiots around I can understand people not liking multi colored rainbow text that you cant read on even a white back, but for text like bold black or dark blue, it's not exactully offensive, and I still go back to the point of 90% of the people don't like it cos they have some crappy black background on.
