I really wish there was a way to stop similar transmitters from connecting together. Currently it is impossible to run say two fluid pipes next to each other with different purposes.
I've had to go to great lengths to stop my Hydrogen and Hydrogen Chloride supplies from mixing together :(
Being able to tell pipes to stop connecting would be amazing!

I think the microblocks covers I've used for this were from the Extra Utilities mod. Put one between the pipes and they don't connect.

Just use the Configurator to change the pipe colors.

Indeed, use micro blocks for now. I'll consider adding color support in the future.

In recent versions cables/pipes/etc seem to have lost microblocks support. Is this a new bug, or is it intentional in favor of replacing it with the aforementioned color support?

Looks like I had the wrong mod installed...in case anyone is wondering, you need the MCMultiPart API installed.
