Answer 2

The original explanation in the comics was that the Guardians of the Universe implimanted it so their Green Lanterns would not be all powerful beings. However, once it started getting silly in the way it was used in comics (infra-yellow, invisible yellow, ect.), it was revealed that the Fear Entity Parallax had infected the central power battery, making it's color, yellow, the Lantern's weakness. After it was purged, the weakness still remained, but the Lanterns can overcome it if they can overcome their fear.
