Nooshin it seems if you paint the walls with low pinkish color and make some oblique with lines in the corner it will be changed to a fantastic room with your furniture .
but if you insisted on having a dark walls i suggest you make a mixed paint with wide white lines in it and change the merchandize of the furniture and light it is better to make the floor with parquet nearly dark .

janishill Here are a few thoughts:

Green would bring life to the spaces and will work with your existing artwork. This color would work beautifully: http://www.benjaminmoore.com/en-us/paint-color/shadesofspring It is dark enough to not show every little mark, but bright enough to keep you from feeling like you are in a dungeon.

Secondly, the pictures in the living room are hung far too high. They look like they are floating off into space. Lower them so they relat to the furniture underneath. They should be 6" - 10" above whatever is under them.

Add drapery panels. Hang them high and wide. (see illustration) They will make your room feel finished.

pillz Agree with comments above. Here is a great site I used to learn how to hang pictures correctly. http://www.apartmenttherapy.com/how-to-hang-you-6174. Curtains would really jazz up the room as well and she is right. Hang the rod all the way to the top of the wall so it hits the ceiling. As for paint colors, I like Benjamin Moores Bennington Gray. It goes with everything.

anoglyfada Agree with other poster....green or a bluish/green shade would bring some life into a rather dull area.
Invest in some colorful to scale size objects.
