Pink squid jigs are my favorite color and seem to catch the most squid.  Orange jigs are also successful when the water visibility is not very clear.  Of course, as is the case with all fishing lures - it depends on the type of squid and the time of the day. Make sure you have a variety of squid jig sizes and colors so that you can change depending on what is working at the time. Keep an eye on your neighbor angler's squid jig if he is catching a lot and try to mimic it.
