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. |

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

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