Best black paint (+ shine level) in black granite tile bathroom?
Bathroom walls will be all black - that's already firmly decided. But which black? Bathroom has shiny absolute-black granite tile flooring and tub enclosure. Vanity top will be similar shine level, vanity itself will be more matte black wood, and much of the bathroom wall on either side is mirrored.
Does anyone have a black paint brand/shade they love, and also recs for the look of satin or semi or gloss or eggshell vs. flat (simply for the look, not for how well one holds up in a bathroom)?
Our walls have been sanded but are not perfectly new, so while I could entertain the idea of a gloss black paint in this bathroom, I'm concerned about wall imperfection show-through. (Anyone successfully done a gloss using a fantastic undercoat of some sort that helps mitigate those issues?)
I also want the walls to look a rich black, and am somewhat concerned that a flat or some blacks could look dull next to the polished black granite.
