Wireshark Coloring Rules Notes

A great site with additional coloring rules offered to the community: http://wiki.wireshark.org/ColoringRules

All default coloring rules are stored in a file Computer> Local Disk> Program Files> Wireshark> colorfilters.

Profile coloring rules are stored in files at USER> Appdata> Roaming> Wireshark> profiles> PROFILENAME> colorfilters

Here is a sample output of the default file:
