I have had great success with black tape on many different light colored backgrounds but I wasn't using discrete components for the sensors and emitters. Instead, I used Omron EE-SY313 amplified infrared photosensors, and plugged them right into the (...) (27 years ago, 17-Apr-97, to lugnet.robotics.handyboard)
