The second incarnation of Superman Red and Superman Blue began as the next in a long line of 1990s storylines, including "The Death of Superman", and "The Death of Clark Kent".

Superman began to develop energy-based abilities after troubles he believed stemmed from a natural evolution of his original powers.[1] His condition was unstable and eventually forced him to adopt a blue and white containment suit. He also gained the ability to turn his powers "off," though this left him as vulnerable as a normal human.

In the Superman Red/Superman Blue one-shot (February 1998), a trap created by the Cyborg-Superman caused Superman to split into two beings who represented different aspects of his personality, though each believed himself to be the original. After an encounter with the planet-threatening Millennium Giants, the two Supermen merged and Superman returned to his normal powers and original costume.[2] The explanation is vague; Superman felt he was "rewarded" for saving the world, although he later claimed in JLA v.1 #20 that he returned to normal when his electromagnetic energy dispersed.

No, the red/blue thing was a few years after the Death/Funeral/Without/Return saga.
