Make-a-lantern!
Jus for fun lets say after all this blackest nights stuff has ended its left the emotional spectrum in complete disarray. The guardians have came to us to reconstruct a new spectrum to help bring back some form of balance to their universe.
We need all ranges of the spectrum from good to bad and light to dark but try to use a new set of colors, powers and sources to empower them. Atleast until all colors have been tried to be used atleast once.
Ok, first shot!
Silver, Arrogance - Granted to the most arrogant of beings. Makes beings as powerful as they believe themselves to be. Power weakens as wielders are shown inferior.
