From what I have read, the two and three color LEDs require voltage to be reversed across them in order to display a different color. The circuit does not allow this.

I always thought the colors switched based on how much voltage was being supplied, but after your post I did some searching and found this:
http://www.superbrightleds.com/TriColor%20LED.htm

These just have one lead for each color in the LED (and use a shared anode or cathode)

MrSaLTy:
Most bi and tri color LEDS that I have used are just like quarterback said.

That type may exist, I haven't come across them personally.  Most are just multiple LEDs in a single package, as was mentioned.
