<Table> <Tr> <Td> Green kryptonite </Td> <Td> Originally red in color , the material debuted in Superman # 61 ( Nov. 1949 ) and did not adopt its characteristic green hue until Action Comics # 161 ( Aug. 1951 ) . Green kryptonite weakens Superman and other Kryptonians . It can and will kill them with long - term exposure . Kryptonians under Kryptonite exposure experience severe muscular weakness , usually to the point of collapse , and excruciating pain , with both conditions progressively intensifying . Kryptonians under Kryptonite exposure usually develop a fever and eventually will lose consciousness before death . Under Kryptonite exposure , the blood of Kryptonians begins turning green , and their skin gradually assumes a green color . <P> Although canonical depictions vary widely , the majority of accounts maintain that although Kryptonite exposure victims experience severe weakness and pain , exposure in itself does not eradicate the victim 's super-powers , except those related to physical strength . Therefore victims retain most of their visual and sensory powers , although Kryptonite itself appears impervious to damage by heat vision . Kryptonite exposure does not compromise the subject 's invulnerability to other forms of injury ; therefore it is not a practical strategy for a villain to first expose the victim to Kryptonite , then kill them with a gun or other conventional weapon . Some accounts maintain paralysis is an effect of Kryptonite exposure , although most depictions show victims still capable of limited movement . Kryptonian characters have been shown to become immune to the effects of green kryptonite due to either long - term absorption of sunlight or extremely high short - term exposure to the sun . Post-Crisis sources establish that green kryptonite is also harmful to humans ; with sufficient long - term exposure , it can result in cancer , as Lex Luthor discovered from a ring with a kryptonite jewel he wore to ward off Superman 's presence . </P> </Td> </Tr> <Tr> <Td> Red kryptonite </Td> <Td> Debuted in Adventure Comics # 252 ( Sept. 1958 ) . Originally red kryptonite simply weakened Superman , but to a greater degree than green kryptonite .

The effects of red kryptonite are sometimes described as lasting exactly 24 hours , but in other accounts the effects may persist up to three days . </Td> </Tr> <Tr> <Td> Anti-kryptonite </Td> <Td> Debuted in Action Comics # 252 ( May 1959 ) .
