So far I thought this was some sort of hack but it turns out that it's a client command or something.
What happened is, this player named [ED]GaRcea came on my server and started chatting with his own red color. The guy is not admin or anything, and even if it was, we don't use color changing scripts for text. If there is anyone who knows this trick or whatever, please respond or send me a PM.

Here's a picture:

Everything is in the script.

Especially if you downloaded this Gamemode from sa-mp forums then I'm pretty sure this guy knows all its tricks.

If the script doesn't have many lines try looking at all its commands to find which one is it.
