I didn't have money to spare for comic books when I was young enough to have been inclined to read them (although I do enjoy superhero TV shows and movies - and now, games). So, not knowing anything about power rings, I was reading online about them recently. I read that a Blue Lantern needs a Green Lantern nearby, in order for the BL to access his ring's full potential (the rationale being that blue rings are powered by hope, and green by willpower, and you can only realize your hopes if you have the will to enact them). Did anyone, in the comics, ever try to create a "turquoise" power ring - combining blue and green, in order to overcome that limitation? I know that every superhero needs limits, in order to avoid his becoming too powerful to write suspenseful stories about him, so such an attempt would have failed for the sake of story-telling. But did they ever try?
Wait, people pay for comic books?
I can't speak to the comics as i haven't gotten around to GL yet in my impossible-without-an-infinite-timeline reading list, but I think that'd go against their whole ridiculous one color one faculty/emotion metaphysics. I only know anything about it from the bad cartoon where his ring worked on its own but he was more effective buffing the green lanterns. Presumably if the guardians were capable of such high level color wheel manipulations they'd have been able to remove the yellow weakness from the green ones as well.
Isn't the White Ranger... I mean *Lantern*... a combination of all the colours?
