What colour should I paint my living room walls? the bookshelf, the couch and other shelves are all BEIGE. the walls...

the bookshelf, the couch and other shelves are all BEIGE. the walls are currently a dark-ish taupe but still beige. i discern like i'm drowning contained by beige.
the room is more long than it is wide-ranging (we live in a condo). as soon as you come within the door, you see the living room. we took out a wall that separated the kitchen from the living room and put a breakfast bar timber which is stained slightly darker than the gloom beige walls.
we enjoy a huge floor-to-ceiling window so it's severely bright but i want to know what colour would look great on the walls with adjectives this beige around.
Answers:    I enjoy a kind of sage green color within our living room and down the hall. Everyone that comes over other comments on it. It's a nice neutral color that match a lot of things.
PURPLE jk i would suggest a wishy-washy color but not ugly possibly a very neutral yellow
