Originally green lantern Alan Scott was vunerable to wood that beijg the weakness of his magic based green lantern in the silver age when hal Jordan was created he was made to be weak to the color yellow and that weakness was used by the villain Sinestro a former member of the green lantern Corp... Currently it has been explained that the yellow impurity of the rings was actually a yellow entity of fear known as parallax which is the avatar of the sinestro corp and now the mythology is written so that all newbies have the yellow flaw until they learn to overcome fear at which point the ring can overcome the yellow impurity and be unstoppable it's only weakness then being a charge limitation

Depending on which Green Lantern we are speaking about. If we are talking about Hal Jordan (the most notable and popular Green Lantern), no, he has the skin tone of a white person for he is a white american. Others have green skin because Green Lanterns are actually a large corps of different alien species (basically a space army) in which the Green Lantern (Hal Jordan) is a part of.
Mogo's, if you read "War of the Green Lanterns" series you can see i in his core and its by far the most powerful.
Originally, the Green Lanterns were vulnerable to anything yellow. Hal Jordan overcame this fear. And, now all Lanterns have overcame it. Except, for the New Recruits, who eventually overcome it. Also, recently, it is known, that the Manhunter's can suck the power out of Green Lantern Rings. Red Lantern Rings, can also dissolve the power. Also, A ring can only hold a charge for around 24 Earth hours. Lego_man2323
