Superman Red/Superman Blue refers to two different comic book storylines published by DC Comics featuring Superman. Silver Age story The original Superman-Red/Superman-Blue tale is an "Imaginary Story" that first appeared in Superman #162 (July 1963). The script was written by Leo Dorfman, with art by Curt Swan. In the story, Superman is compelled to finish a list of unaccomplished goals, including the enlargement of the Bottle City of Kandor and eliminating crime and evil from Earth. In order to accomplish these goals, Superman invents a machine, powered by various types of Kryptonite, that will increase his intelligence. The machine works, increasing Superman's intelligence a hundredfold, but with the unexpected side effect of splitting Superman into twin beings, one outfitted in an all-red Superman costume and the other in an all-blue version. The twins name themselves Superman-Red and Superman-Blue. The Supermen, using their enhanced intellects, first repair Brainiac's "enlarging ray". They then create a means to bring all the fragments of Krypton together, creating a "New Krypton" (eliminating all existing kryptonite in the process), and successfully enlarge Kandor on its surface, freeing its citizens from their bottle prison. At the urging of Lori Lemaris, the Supermen create an underwater world for the citizens of Atlantis and arrange an interstellar voyage to transport them to their new home. The two Supermen go on to create an "anti-evil" ray which can cure criminal tendencies in anyone. They place the ray into satellites in orbit around the Earth, curing not only villains such as Lex Luthor and Mr. Mxyzptlk, but reforming Communists such as Nikita Khrushchev and Fidel Castro. The reformed Luthor goes on to invent a serum that cures all known diseases, which the Supermen put into the water supply. Supergirl then releases the Phantom Zone inmates, also reformed by the ray, and they immigrate to New Krypton in a spaceship provided by the Legion of Super-Heroes. With nearly all of the world's problems solved, the two Supermen now have the opportunity to deal with personal matters. The split allows them to resolve the love triangle between Superman, Lois Lane, and Lana Lang. Superman-Red proposes to Lois, while Superman-Blue asks Lana to marry him. Each woman claims her own Superman, and they have a triple wedding: Superman-Blue and Lana, Superman-Red and Lois, and Lucy Lane marrying Jimmy Olsen (since Lucy need no longer wait for Lois to marry before she does).
