Does the bounce beam sorta act like a sonar for colors, bouncing a beam of the wall of the feed, recieving the beam, and analyzing the color to see if it matches the color of the feed (and is that why it wont read dark colors, because the inside of the feed is pretty dark due to lack of light) And does the break beam send out a continuos beam, and only shoots when the beam is broken (hence the hole in the side of the feed)? I'm just guessing, i don't know how they work. (really, i don't)

EDIT: oh, i see now. i was right about the broken beam, but totally wrong on the bounce beam. thanks for the site, Badinflewinse.
