Red Lanterns are ineffective on their own against Black Lanterns, or any other Lantern corps. Red Lantern Vice was able to kill so many on Oa of them during the Blackest Night because the Black Lanterns around him had recently/were currently been/being blast(ed )by energy from Green Lantern Power Rings. Guy Gardner is able to kill Black Lanterns because he had both a Green and Red Power Ring.

Harold: The corps on the far edge of the spectrum (Red + Violet) have strong effects on their wearers; a Red ring controls its wearer as much a Sapphire ring controls its wearer. As you get closer to the middle, the effects are less severe until you get to the middle, Willpower, which has no direct effect on its wearer. But here's the short version:

Red Strong against: All other corps; once you have a ring on, it's impossible to resist the rage. Weak against: Blue. Only a Blue Power Ring can reverse the effects of a Red ring (Sapphire Rings can maintain a heart stopped due to the effects of a Red Ring.)

Orange Strong against: All other corps; again, the emotion of avarice is extremely overwhelming. Weak against: A Blue Lantern Ring has been seen to abate/dull the effects of an Orange Ring. Red and Violet can overwhelm the avarice felt.

Yellow Strong against: Green, Blue (when not reinforced by Green) Weak against: Green + Blue together, Red, Violet, Orange, Indigo

Green Strong against: Yellow, if the user is willful/unafraid Weak against: All other corps

Blue Strong against: Yellow, when reinforced with Green Weak against: Yellow, if no Green is present, Orange

Indigo Strong against: Equally powerful against all other corps (no obvious benefit fighting a Green Lantern over Larfleeze.) Weak against: Red, Violet

Violet Strong against: Red (able to maintain a stopped heart until a Blue ring can heal the Red Lantern,) Yellow 'Weak against: Red
