http://en.wikipedia.org/wiki/Kryptonite#Forms_of_kryptonite
The various known forms of kryptonite in the Superman comics include:
Green Kryptonite: In superpowered Kryptonians, causes immediate physical pain and debilitation and kills within hours. Has no short-term effects on humans (though strictly in post-Crisis continuity, long-term exposure is apparently lethal to humans) or non-superpowered Kryptonians. In one early Silver Age story, Superboy built up immunity to specific chunks of Green Kryptonite through repeated non-fatal exposure, as seen in the story "The Great Kryptonite Mystery" (Superboy (1st series) #58, July 1957). The most common form of kryptonite.
Red Kryptonite: Created from Green Kryptonite that passed through a mysterious red-hued cloud en route to Earth. Red Kryptonite inflicts random effects on Kryptonians, typically creating an initial "tingling effect" in those affected. Each specific chunk of Red Kryptonite has the same effect on all Kryptonians, but no two chunks have the same effect. Red Kryptonite effects typically last for 24–48 hours (though sometimes as long as 72), after which the Kryptonian in question is always immune to that specific chunk of Red Kryptonite. Superman has suffered the following effects upon exposure to various pieces of Red Kryptonite: being turned into a dragon, a non-powered giant, a midget, an ant-headed humanoid, a lunatic, or an amnesiac; made unable to see anything colored green; growing incredibly long hair and beard; being rendered totally powerless; losing his invulnerability along the left side of his body; being split into an evil Superman and a good Clark Kent; rendered unable to speak or write anything but Kryptonese, the language used on Krypton; growing an extra set of arms; swapping bodies with the person nearest him upon exposure to it; and rapid aging. In post-Crisis continuity, Red Kryptonite first appeared as an artificial construct of Mr. Mxyzptlk; a second variety was later revealed as a synthetic variant created by Ra's al Ghul, using notes he stole from Batman.
Gold Kryptonite: Removes superpowers from Kryptonians permanently; however, in one story, a temporary antidote was developed that negated this effect for a short period of time. For obvious reasons, this variety was little used in Superman stories. It played key roles in both the 1982 miniseries "The Phantom Zone", and in the 1986 noncanon tale "Whatever Happened to the Man of Tomorrow?" Additionally, it appeared briefly in the post-Crisis DC Universe, when Superman used it on a trio of Kryptonian criminals while visiting the Pocket Universe (Adventures of Superman #444, Superman (volume 2) #22). As cited in World's Finest Comics #159 (1966), Gold Kryptonite has an effective range of two feet.
White Kryptonite: Kills all plant life, whether Kryptonian or not. Induces decay immediately upon exposure, with a range of about 25 yards. The most prominent use of White Kryptonite in the comics was to destroy Virus X, which was revealed in a storyline in 1968's Action Comics #362-366 to actually be a form of plant life.
Blue Kryptonite: The result of using Professor Potter's "duplicator ray" on some Green Kryptonite. Blue Kryptonite kills Bizarros, but has no effect on Kryptonians or humans.
Anti-Kryptonite: Has no effect on superpowered Kryptonians, but has the same effects as Green Kryptonite on non-superpowered Kryptonians. This version of kryptonite is what killed most of the residents of Argo City in the pre-Crisis comics. It was likely introduced to cover a writer error, as the original Argo City story does not call it Anti-Kryptonite. Post-Crisis, it is the power source of Ultraman, Superman's evil counterpart who lives in an alternate antimatter universe.
X-Kryptonite: Created by Supergirl while experimenting with Green Kryptonite in hopes of finding an antidote. It has no effect on Kryptonians, but bestows temporary superpowers on Earth lifeforms, most prominently Supergirl's pet cat, Streaky. Not to be confused with Kryptonite-X.
Jewel Kryptonite: Jewel Kryptonite amplifies the psychic powers of Phantom Zone residents, allowing them to project illusions into the "real world" or perform mind control. It was made from what was left of a mountain range on Krypton called the Jewel Mountains. (It is shown in one comic story to be used by Zod and Ursa outside the Zone in the "real" world as well, to blow up the piece they had and transport themselves back to the Phantom Zone. So it is probable that any Kryptonian can make use of Jewel Kryptonite as long as they are in close proximity to it.) In the Post-Crisis Silver Age miniseries, a "prismatic gem from the Jewel Mountains of Krypton" was used by the Injustice League to amplify the psychic powers of the Absorbacon, but was not referred to as Jewel Kryptonite.
Slow Kryptonite: A modified variety of Green Kryptonite produced by a Terran scientist that decelerates the speed of nerve impulses and movements of both Kryptonians and Terrans. Appeared in The Brave and the Bold #177.
Purple Kryptonite: Gives Kryptonians mental/psychic powers, allowing them to create matter out of thin air. This effect only lasts 12–24 hours and all matter created disappears with the powers.
Magno-Kryptonite: A piece of kryptonite that is magnetically attracted to all substances originally from Krypton, according to Superman's Pal, Jimmy Olsen #91.
Bizarro Red Kryptonite: Affects humans the same way Red Kryptonite affects Kryptonians. Appeared in Superman's Pal, Jimmy Olsen #80.
Pink Kryptonite: From an alternate timeline in a 2003 Supergirl storyline by Peter David, this variety of kryptonite apparently turned heterosexual Kryptonians into homosexuals; it was seen in just one panel, with Superman giving flattering compliments to Jimmy Olsen about his wardrobe and decorative sense. It spoofs the many varieties of kryptonite introduced over the years, as well as the more "innocent times" of the Silver Age (Lois Lane is depicted in this story as not understanding what's gotten into Superman). This version of kryptonite has not been used in mainstream comics continuity.
Kryptonite-X or Kryptisium: A form of filtered/purified kryptonite. Professor Emil Hamilton used the term "Kryptonite-X" (The Adventures of Superman #511, April 1994, page 13) to describe the substance that restored Superman's powers after a confrontation with the villain known as the Cyborg Superman in Engine City (Superman (volume 2) #82, part of the "Return of Superman" storyline). This substance was created when the Cyborg used a huge chunk of kryptonite in an attempt to finally kill the weak, powerless, recovering Superman. The Eradicator, who had fashioned a faux-Kryptonian body using a Kryptonian matrix, jumped in front of Superman before the release of the kryptonite energy could kill him. Despite the Eradicator's efforts, the kryptonite energy hit Superman, but instead of killing him, it transferred all of the characteristic Kryptonian powers from the Eradicator to Superman, as well as saturating Superman's body with a purified/filtered form of kryptonite. This substance eventually led to Superman becoming an over-muscled giant, due to his accelerated sunlight absorption and overstorage of energy. This kryptonite is not to be confused with X-Kryptonite.
Black Kryptonite: Black Kryptonite was first introduced in the Smallville television series, in the fourth season premiere episode "Crusade," as kryptonite with the potential capacity to split a person or a person's personality into two separate entities. It later made its first appearance in a DC comic in September 2005's Supergirl #2, where it apparently possessed the same abilities. In Supergirl #3, Luthor used Black Kryptonite on Supergirl, which caused her to split into two separate people, one wearing Supergirl's traditional costume, and another wearing a black-and-white version. Her black-and-white costume is similar to the one that Superman was wearing when he returned from the dead.
[edit]
Simulated kryptonite
Green Lantern Corps rings can be used to emit simulated Green Kryptonite radiation. This radiation is apparently just as powerful and painful to Superman and other Kryptonians as the genuine rays.
Synthetic kryptonite (usually the green or red variety) has been successfully produced by Lex Luthor, Batman, and Ra's al Ghul in the comics. It has proven to be less powerful than genuine kryptonite, to be extrememly difficult to create, and to have a short half life that renders it useless after a short period of time.
Magic: Users adept at the use of magic may be able to create kryptonite, such as Mr. Mxyzptlk did in the "Krisis of the Krimson Kryptonite" storyline (though his version of Red Kryptonite differed from the traditional version in its workings).
[edit]
Hoaxes
In the comics, several varieties of kryptonite that turned out to be hoaxes include:
Silver Kryptonite: A fictional variety of kryptonite that was used in a hoax perpetrated by Superman's friends, in honor of the 25th (or "silver"😉 anniversary of Superman's arrival on Earth. (For the Silver Kryptonite created by Brainiac in the television series Smallville, see below.)
Yellow Kryptonite: Another fictional variety, this one was used in a hoax masterminded by Lex Luthor.
