The Green Lantern Corps Power Rings each represent a different emotion. The red ring is rage, orange is greed, yellow is fear, green is willpower, blue is hope, indigo is compassion, and violet is love.
Green Lantern is the name of several superheroes from the fictional DC Universe, all of whom are characterized by a power ring and the ability to create solid constructs with the ring.
The first Green Lantern (Alan Scott) was created by writer Bill Finger and artist Martin Nodell in All-American Comics #16 (July 1940).

The Sinestro Corps is a group of fictional characters, a villainous analogue to the Green Lantern Corps in the DC Universe, derived from the emotional spectrum. It is led by the supervillain Thaal Sinestro.
The Parallax entity is a space parasite that is the embodiment of fear that was imprisoned within the Central Power Battery on Oa. As time passed, the entity became known as the yellow impurity, the cause for the power rings' weakness to the colour yellow.
Kyle Rayner is a fictional comic book superhero appearing in books published by DC Comics, usually in those starring the Green Lantern Corps, an extraterrestrial police force of which Rayner is a member. Created by writer Ron Marz and artist Darryl Banks, Rayner first appeared in Green Lantern vol. 3, #48 (1994), as part of the "Emerald Twilight" storyline, in which DC Comics replaced Green Lantern Hal Jordan with Rayner, who was the sole Green Lantern for years until the late 1990s. During this period he was also briefly known as Ion.
Following Jordan’s return to Green Lantern status in the 2004–2005 limited series Green Lantern: Rebirth, and the 2005 crossover event "Infinite Crisis", Rayner returned to his alias of Ion. After the events of the "Sinestro Corps War", Rayner returned to his original role as a Green Lantern officer, along with a promotion to Honor Guard Illustres of the Corps. Later on he becomes a White Lantern following the mastery of all seven lantern rings.
Harold "Hal" Jordan is a DC Comics superhero known as Green Lantern, the first human shown to join the Green Lantern Corps and a founding member of the Justice League of America. Jordan is the second DC Comics character to adopt the Green Lantern moniker. Jordan was created in the Silver Age of Comic Books by John Broome and Gil Kane, and made his first appearance in Showcase #22 (October 1959) to replace the original Green Lantern Alan Scott from the Golden Age of Comic Books.
In 1994, the story Emerald Twilight saw Hal Jordan turn into the supervillain Parallax. Later, in the Zero Hour miniseries, he attempts cosmic genocide. He was replaced by Kyle Rayner as the new Green Lantern for the Modern Age of Comic Books. In the 1996 crossover story "The Final Night", he attempted to return to his heroic roots by dying to save the Earth, and later returned as a spirit of redemption in the persona of the Spectre. Hal Jordan was resurrected in the 2004 miniseries Green Lantern: Rebirth, which revealed that Parallax was actually an alien parasitic entity that influenced his prior villainy. He subsequently returned to the Green Lantern Corps and became the protagonist of the subsequent volumes of Green Lantern.
The emotional spectrum is a fictional concept within the DC Universe, primarily portrayed in Green Lantern titles. The colors of the emotional spectrum are harnessed as power sources by various fictional organizations wielding power rings.
The concept was created and developed by DC writer Geoff Johns from 2007-2009 as a reinterpretation of part of the Green Lantern mythos and has grown in prominence in the DC Universe with Johns' own ascension to his current position as DC's Chief Creative Officer in 2010. Guy Gardner
"Blackest Night" is a 2009–2010 American comic book crossover storyline published by DC Comics, consisting of an eponymous, central miniseries written by Geoff Johns and penciled by Ivan Reis, and a number of tie-in books. "Blackest Night" involves Nekron, a personified force of death who resurrects deceased superheroes and seeks to eliminate all life and emotion from the universe. Geoff Johns has identified the series' central theme as emotion. The crossover was published for eight months as a limited series and in both the Green Lantern and Green Lantern Corps comic titles. Various other limited series and tie-ins, including an audio drama from Darker Projects, were published.
The storyline was first mentioned at the conclusion of the "Sinestro Corps War" in Green Lantern vol. 4, #25. As the war between the Green Lantern and Sinestro Corps reaches its climax, the four Green Lanterns of Earth—Hal Jordan, Guy Gardner, John Stewart, and Kyle Rayner—are told by the Guardians Ganthet and Sayd of the Blackest Night prophecy. According to the prophecy, the two existing Corps would be joined by five new ones, each driven by a specific emotion and empowered by a specific color of the emotional spectrum, leading to a "War of Light" that would subsequently destroy the universe. Johns says the prophecy has its origins in the story "Tygers" by Alan Moore, which touches on the rising up of the Guardians' enemies the Weaponers of Qward, Ranx the Sentient City, and the Children of the White Lobe,the destruction of the Green Lanterns, and shows Sodam Yat and Mogo dying. Atrocitus, however, denies the accuracy of this prophecy, suggesting that it blended the Blackest Night and the Sinestro Corps War with pure falsehood.
