I think the black thing was just a stylistic choice to show us that something strange was happening. I don't think she actually glowed black, or she'd glow blakc everytime she uses her semblance. And then everyone would know she does during a fight, which means they would know what it is, which means her whole 'subtlety' thing is null and void and everyone just kind of indulges her idea that not many people know what her semblance is.
