Sorry to state the obvious but don't forget to
place a resistor on either of the two colour pins or one on the
ground leg

Hi-
You can wire pin2 to 5V, and pins 1&3 to two different output pins on the PIC.
If you write a zero to the pin connected to pin1, then current will flow fron
teh 5V to the PIC pin into ground inside the PIC, likewise the other pin.  If
you make them both zero, you will turn on both colours.  If a pin is a 1, then
both sides of the LED are at 5V, so no current flows, and the LED is off.
