How can i have color in my name on multiplayer?

Yeah, all you got to do is put in ^ and a number.

For Example:

^4 is blue. I don't know the rest of the colors.

1=red
2=green
3=yellow
4=blue
5=cyan
6=pink
7=white
8=black
9=red (? either that or white again)
0=black

Note: 8 & 0 don't work in your name. Sure, it'll show up as black in chat, and in the console (hard to see) but in the score table it will simply show up as white.

The way to get black text in your name is to use a double ^ with 0.

So I could have a name like ^^0Kurgan, which would appear as ^Kurgan (in all black).

A few mods out there allow black to show up without that trick though...
