No - that's the neat trick about it - red and green LEDs have different voltages, so only the one with the lower voltage will light.
Red = 1.8V, Green = 2.2V (approx)
If you want them the other way round, put a diode in series with the red, then red+diode = 2.5V, green=2.2V.
Ah.... got it. Thanks. That will simplify things for me not having to run as much wires. Thanks. :)
