Which of the following rings from the DC Comics' "Lantern Corps" are classified as Parasitic?

The Indigo Power Ring, classified as the Indigo (Compassion) ring, is considered parasitic because it requires the wearer to have little to no compassion of their own in order to function properly. Unlike other rings from the various Lantern Corps, which draw power from the emotional spectrum, the Indigo ring is unique in that it does not actually create its own energy. Instead, it taps into the emotions of others, forcibly extracting the compassion from people in order to sustain itself. This parasitic nature makes it distinct and sets it apart from the other rings within the DC Comics Lantern Corps.
