    So you don't have a seperate ground.

    That means every LED up stream of the one that goes red will go out.

    If you accept that limitation, dump the transistor and the 10k resistor, not required.

    Connect one LED cathode to NO, one cathode to NC and the common anode to your 190 ohm off 5V.
