your im and chat line (and other notifications lines) is there :

Code:

PatternCommunicationIM=30;1;0;b;9d80400002ff03ff02ff03ff71080000;9d800000
PatternCommunicationSMS=30;1;0;b;9d80400002ff03ff02ff03ff71080000;9d800000
PatternCommunicationEmail=30;1;0;b;9d80400002ff03ff02ff03ff71080000;9d800000
PatternCommonNotification=30;1;0;b;9d80400002ff03ff02ff03ff71080000;9d800000

again the colors commands be bold....

so what you need its to replace the ''colors commands digits'' of your choice
