[Crazy Jetty]

I don't think Violet has any real effect on other colors. But it makes more sense for the Sapphires to have an effect over Red than it does the Blue. Love trumps Hate.

Blue is worthless without Green, because Hope without Will is empty.

Green is powered up by Blue, because Will is empowered by Hope.

Yellow is drained by Blue, because Hope overcomes Fear.

Red is overcome by Blue, because Hope sooths Rage.

Blue is uneffected by Orange, because Hope overcomes Greed.

Yellow beats Green, because Fear breaks Will.

Rage burns all but Blue.

So the ones left out are Violet and Indigo. Love and Compassion And honestly they make more sense on that chart than some of the uses of Blue. Like I said earlier, it makes more sense for Love to trump Rage. It also makes more sense for Compassion to trump Avarice.

Of course one of the things I liked about the show is that it wasn't afraid to make changes to the lore (The red lanterns aren't absolutely dominated by their rings, turning them into fully functional characters). So with the relationship between Aya and Razer, they may have been intending to make some modifications.
