It sounds like you may have the electronics figured out already, but in case you're still working on it... I really like using the DX RGB LED along with a 3.7v battery and a latching switch (plus lens/lens holder from TCSS) for a basic electronics setup. The blue and green dies can be directly wired to a 3.7v battery, though the red needs a resistor. As a bonus, you can easily get a variety of colors with the same LED. It's worth noting that the +/- signs printed on the LED are reversed, or at least they use to be, and shipping can take a looong time (they ship quickly, but my last order was over a month in transit for LEDs and some batteries).
