It's been a long time since I wrote a blog, but I found this cool.

How to make your Profile name in COD:BO have color.

First, you are gonna have to go to the select profile screen. Highlight yours, and press ©.
It will be empty. Don't worry, this won't erase you profile stats. Press Shift, ^ (in 5 spot) and then a number. The ^# will dissapear, and whatever you typed would be that color.
COLORS:
1=red
2=green
3,6,7=yellow
4=dark blue
5=light blue
8,9=grey
Heres an example:
If I typed (without spaces):
^3 007 ^1 Jesse
it would look like:
007Jesse

Hope you found this useful!
