Tiny piles of redstone used without palette and brush should result in a uncolored wire (not a light grey one). This should be the only one that sends a signal to all colors as i/o. So that when we connect a white wire on a circuit within a circuit only sends a signal to a white wire, orange to orange wire, ... and the uncolored one to every color. This also could solve the bundled wire issue with circuits within circuits.
