I know players typically use the color codes on Full Tilt to identify 'player types,' but I have another use for them that might be of use.

I've always used the color codes to identify players according to how many tables they were playing. For example, if a player is on one table I would assign a bluish-green color to him because I assume most players who are only playing one table are playing a certain style or are of a certain skill level.

Players who are on 4 tables get a solid orange color. These are the multi-tabling Reg's for the most part, and I know about what to expect from that type of player.

Players who are on 8 tables get a solid red color. This is where the color codes are really valuable. These players are infinitely exploitable. They are too busy with action on all 8 tables, so I will push a little harder against them because I know they are only playing strong hands. A raise or a check-raise from this player is mostly 'the goods.'

You will find these players have to back down most of the time when facing strong aggression, and they can be destroyed when playing out-of-position.

Try setting your color codes to identify players based on the number of tables they are playing and you will get a quick overview of you can exploit and how.
