I love how the poster-boy for Superman starts his argument trying to deny the existence of Kryptonite, or anything like it. You know it will be there, in some way, shape, or form. The writers add this stuff in, not me:
-------------------------------------------
Green: Originally red in color, the mineral debuted in Superman #61 (November 1949) and did not adopt its characteristic green hue until Action Comics #161 (Aug. 1951). Green kryptonite weakens Superman and other Kryptonians. The character has been shown to become immune to the effects of green kryptonite due to either repeated non-fatal exposure,[7] continuous long-term absorption of solar radiation,[8] or extremely high short-term exposure to the sun.[9] Post-Crisis sources establish that green kryptonite is also harmful to humans given sufficient long term exposure, resulting in cancer as Lex Luthor discovered as a result of a ring with a kryptonite jewel he wore to ward off Superman's presence.[10]
Red: Debuted in Adventure Comics #252 (Sept. 1958). Originally just weakened Superman, but to a greater degree. Later caused bizarre behaviour and transformations.
Anti-Kryptonite: Debuted in Action Comics #252 (May 1959). Harmless to Kryptonians, but has the same effect as the green variety on normal humans. The power source for one version of the character Ultraman, Superman's evil counterpart.[11]
X-Kryptonite: Debuted in Action Comics #261 (Jan. 1960). Created by the character Supergirl in an unsuccessful attempt to find an antidote to green kryptonite. Harmless to Kryptonians, the mineral gives normal lifeforms superhuman abilities, as in the case of Supergirl's pet cat Streaky. Revised in Superman Family #203 (Oct. 1980) to have the same effect as the green variety on kryptonians.
Blue Debuted in Superman #140 (Oct. 1960). An "imperfect" form of kryptonite which affects the imperfect character Bizarro in the same way the green variety of kryptonite affects Superman.
White: Debuted in Adventure Comics #279 (Dec. 1960). Kills all plant life, from any world.
Red-Green: first variety Debuted in Action Comics #275 (April 1961). An alloy created by the villainous character Brainiac, it caused Superman to mutate, temporarily growing a third eye in the back of his head.
Gold Debuted in Adventure Comics #299 (Aug. 1962). Kryptonite affected by atomic radiation, and capable of permanently removing a Kryptonian's ability to process yellow sunlight, which in turn nullifies all superhuman abilities. Post-Crisis, this kryptonite only removes a Kryptonian's powers temporarily.[12]
Red-Green-Blue-Gold: Debuted in Superman #162 (July 1963). An imaginary story in which Superman combines the minerals to power a device to boost his intelligence. An explosion causes a mishap and the character is split into two separate beings ("Superman-Blue" and "Superman-Red"), both of whom possess enhanced intelligence.
Silver: Debuted in Superman's Pal, Jimmy Olsen #70 (July 1963). Revealed by Jimmy Olsen to be a hoax. In Superman/ Batman #49 (Aug. 2008), silver kryptonite was re-introduced, on this occasion shown to be authentic as it causes Kryptonians to suffer from delusions.
Jewel Debuted in Action Comics #310 (March 1964). Fragments of Krypton's Jewel Mountains. Amplifies the psychic powers of the criminals imprisoned in the Phantom Zone, allowing the characters to project illusions or perform mind control.
Bizarro Red: Debuted in Superman's Pal, Jimmy Olsen #80 (Oct. 1964). Affects humans the same manner that red kryptonite affects Kryptonians.
Red-Green : second variety Debuted in Superboy Comics #121 (June 1965). Causes Superboy to lose his powers permanently but Phantom Zone criminal Vakox unwillingly cures him, restoring his powers.
Red-Gold: Debuted in Superman #178 (July 1965). Temporarily deprives Kryptonians of their memories.
Magno-Kryptonite Debuted in Superman's Pal, Jimmy Olsen #92 (April 1966). Artificially created by the villain Mr. Nero, the mineral is magnetically attracted to all substances originally from Krypton.
Red-Green-Gold: Debuted in Superman #192 (Jan. 1967). An imaginary story in which the alloy permanently removes the character's abilities and memories of ever having been Superman.
Slow Debuted in The Brave and the Bold #175 (June 1981). A modified variety of green kryptonite produced by supervillan Metallo that affects humans in a manner similar to the green mineral.
Kryptonite-X: Debuted in The Adventures of Superman #511 (April 1994). A one-time fluke, Kryptonite-X was created when the character the Eradicator filtered a harmful barrage of kryptonite discharged by the villain Cyborg Superman at Superman. The result was actually beneficial: "supercharging" the character and restoring his ability to process solar radiation.
Pink Debuted in Supergirl vol. 4 #79 (April 2003). Seemingly turns Kryptonians gay. This type of kryptonite was mentioned in a single panel in a story that was a satire of the plots of the many Silver Age comic stories (such as those above in this list) which featured some strange new form of kryptonite.
Black: Debuted in Supergirl #2 (vol. 5, Oct. 2005). Can split a Kryptonian into two separate entities: one good and the other evil.
Orange: Debuted in Krypto the Superdog #4 (Feb. 2007). Gives super abilities to any animal that comes into contact with it for 24 hours.
Periwinkle: Debuted in Superman Family Adventures #9 (March 2013). A non-canon story, exposure causes Kryptonians to lose all inhibitions.
