Soulmate AU where everything is monochrome except for people who have found their soulmates, and you only see color when you meet your soulmate.
Elaboration: Once you can see color, everyone is in color to you, even people who haven't met their soulmate yet. When your soulmate dies, you can still see color; however, if they are killed by you or they kill themselves, then you will still go blind.
