Lantern Rings

I want to get a power ring, but not just any power ring. I've actually given this a good bit of thought. I've never seen a male Star Saphire, so a violet ring can be eliminated. I also don't want my ring to fill me with rage or avarice, so red and orange are out. Black is completely out of the question since I don't want to be a zombie lantern, and yellow is also undesirable because it could corrupt me like Sinestro. That leaves green, blue, indigo and white if I didn't have to join their corps. If I did, I would probably choose blue or white because the Guardians lie too much for my comfort and members of the Indigo Tribe have no names and not nearly enough individualality.
