I'm not in a position to test at the moment (and I can't find my reference), but I could have sworn that I read somewhere recently to the effect that tagged items can pass through normal tubes, but untagged ones can not pass through colored tubes. I think I've also observed this as well. Apologies if I'm wrong!
