Hello, I am painting the living room and the entry foyer and the second floor all one color more than likely I’m going with classic gray matte and for the ceiling and trim I’m going with 75% lighter from the classic gray as I don’t want a huge contrast between the trim and the wall I’d like it to be a nice and muted flow. My question is:

I have recessed ceiling and I also have a double face fireplace. Do I need accent wall or accent ceiling in the recessed ceiling see photos please the current colors are old as we just started painting the walls.

My bookcase will be dark stain of charcoal grey.
