Ok, so there was a way that was found to get color in chat that can be seen by everyone, not just you. Below are the codes you have to do in order to get color. It's done by a feature called "chat tags".
[b] - bolds text
[c="magenta"] - This text will be magenta.
[bg="grey"] - Any kind of background you want.
You can also do them together. Like so...
[b][c="magenta"][bg="grey"]Insert text here.
So yeah, this is pretty self-explanatory. You can use any color you want, as it's not limited to the colors of the IRC. Also, the easiest way of using this if you wanna bold, color, and have a background you can just copy and paste the code into the chatbox. You can also use each one by themselves if you wanted too.
