By the way, maybe some people would like to see more colors added. I mean, being able to send messages using "true colors" (24/32 bits) for example.
I'd like to highlight the fact that the colors' implementation is client dependant (so for example, the display may not be the same under mIRC and xchat, if any).
What's more, the current implementation needs to embed color codes using special characters. I'm not sure it can be expanded so as to allow for "abritrary" colors to be sent.
