Well eventually both my tool and Jim's tool will be released for public consumption. Mine is ready to be released, but it lacks a UI. It's all command line based. I've automated everything I can. I don't see a point in adding in a UI just yet.
No, my colour list is kept simple in a RGB format. I complied the list myself. The same colour list is used across BF3, BF4 and any other game I scan.
You are right. At the moment, I've only detected a handful of cheaters on BF4. But I think that is down to PunkBuster not being able to defeat current PBSSes blockers.
PBSS Collector is the old ancient software that AC.I now maintain. The reason I created/programmed my own application was to speed things up. I haven't used PBSS Collector in months, but I would imagine that you have move all those PBSSes you want to scan into its respective folder.
