So many grays turn blue. after much trial and error for bdrm, bath and water closet , i'm happy with Benjamin Moore Horizon and Behr ultra in Burnished Clay. Neither look great on the card but they dry to a soft neutral gray. worth getting samples to try.

Firstly, one can play a lot with furnishings if you are staying in a rented apartment. those white walls are nothing but a clean canvas and you can really use colors through your furnishings like cushions , upholstery, curtains , rugs etc to add colors . Secondly , instead of wall shelves etc add small side tables on emptycorners you get etc which gives you platform surfaces to display your nick knacks.. You get many freestanding display shelves online and in market where you don't have to use screws in wall. :)

Greetings From Dream Design, As per your Requirements we are suggestion you some changes -White color -where It is Grey -Dark Cream -Where Blue as it will highlight that area and also well goes with Bricks -and Trims take Dark cream -For Shutters you can also use Cream color So use the White and dark cream with combination as brick part is already dark If you need more help Pls mail us. Thanks Dream Design

White combination will look good otherwise if all dark then kitchen will look small
