HOW TO CREATE COLOURED NAMES IN COD2 & COD4
1. FIND YOUR "config_mp.cfg" FILE. THERE ARE 2. THE ONE YOU NEED IS IN THE FOLDERS BELOW. NOT IN YOUR MOD FOLDER.
THESE ARE THE LOCATIONS OF MY "config_mp.cfg" FILE ON WINDOWS 7.
Call of Duty 2
C:\Program Files (x86)\Activision\Call of Duty 2\main\players\JiMBO
Call of Duty 4
C:\Program Files (x86)\Activision\Call of Duty 4 - Modern Warfare\players\profiles\JiMBO_34th
OPEN THE FILE WIYH NOTEPAD. VERY CONFUSING AS IT CONTAINS ALL THE KEY PRESSES ETC YOU SET UP IN OPTIONS.
GO TO THE MENU BAR - EDIT - FIND AND TYPE IN THE BOX YOUR NAME AS ON YOUR FOLDER.
I WOULD TYPE IN "JiMBO". THIS WOULD FIND THE NAME IN THE COMMAND 
seta name "JiMBO [34th]". THE NAME BETWEEN THE QUOTES IS SHOWN IN-GAME. 
IN THIS FORMAT IT CONTAINS NO COLOURS. THESE ARE THE COLOUR CODES.
// ^1 = Red 
// ^2 = Green
// ^3 = Yellow
// ^4 = Blue
// ^5 = Cyan
// ^6 = pink/Magenta
// ^7 = White
// ^0 = Black

THE SYMBOL "^" IS Shift 6. SO RED = (Shift)6 1 OR ^1.
TO MAKE YOUR NAME ALL RED THEN IT WOULD BE        ^1JiMBO
THE [34th] IN THE CYAN COLOUR WOULD BE ^5[34th]. TOGETHER = ^1JiMBO ^5[34th]. 
COPY AND PASTE YOUR CREATION INTO THE COMMAND BETWEEN THE QUOTES AND SAVE.
EG: seta name "^1JiMBO ^5[34th] " 
YOU CAN CREATE MULTIPLE COLOURS BUT I THINK THE LENGTH IS 24 CHARACTERS. THIS INCLUDES THE SYMBOLS AND SPACES. ^1JiMBO ^5[34th]  = 16 CHARACTERS.
SO THE LONGER THE NAME THE FEWER COLOURS. IF YOU HAVE THE CLAN NAME ^5[34th] AFTER YOUR NAME THIS ADDS 9 CHARACTERS INCLUDING THE SPACE AFTER YOUR NAME,
LEAVING YOU 15 CHARACTERS FOR YOUR NAME AND COLOURS.
YOU CAN ALWAYS TYPE THE NAME INTO MULTIPLAYER NAME IF YOU DON'T WANT TO EDIT A CFG FILE.
