I am also not a programmer, but I believe I can fill in some of the information for you. Firstly, the hanging tetras do not have the green vision panels. Secondly, if you want your robot to find a loading zone, I would assume you would use the same find color function as when finding a vision tetra, but (if it's possible), to look for the two color blobs that have x distance in between them (the two loading zones). This would decrease the chance of it heading elsewhere, (and a gyro + shaft encoder on your wheels could approx. the location with some trig functions), but keep in mind, this is just supposition. Also, I'd suspect that if you did this in the above manner, your code would be overly cumbersome and probably fill up way too much room on the RC. I am sure that there are no vision panels on the hanging tetras though. Hope this helped.
