Carpet line differences

[ChaosX73]

Hey, I'm the autonomous programmer for my team. We have been testing those shnazzy new line tracking sensors, but they are very sensitive, so my question is this: how are we supposed to tell the difference between the caution lines on the floor and our team color lines at the end of the tracking line? I mean, if the sensors are supposed to register light differences, and its going to tell the difference between the team color lines and the carpet, then they're definitely going to tell the difference between yellow tape and the carpet.

I mean, I could program it so it has to register the arrival at the T section twice before it goes through the hanging program, or I could program a wait in the program so it doesn't try reading for the T section until after a couple seconds, but both of those solutions could be buggy.

What are your ideas for getting past this point?
