I was finally able to post pictures. Thank you!

I think I would want to drywall it up to the ceiling, it creates a choppy look. Otherwise I would keep it the same color as the other walls and put what you have hanging over the sofa and get some nice art for behind the sofa.

You need some colorful large art work somewhere. Either on that wall or behind the sofa.

I'm with cubby 14. Get a large skyscape art work that incorporates the accent wall dark blue but gives you a feeling of the sky--like a window. Alternatively get a long horizontal mirror to reflect the light come in from your doors.

I see what you were trying to do with the dark wall, but I think you’ve made a chopped up space look even more chopped up—particularly when you can see that the navy wall continues into the kitchen but changes over to white. I would paint that wall white again. If anything, to distract from the half-wall, I would swap out the track lighting in the living room for a more stylish fixture. Perhaps you can put down area rugs with color in them if you want to inject color into the space or visually separate the dining room from the living room.

An amendment to my prior post—put down a navy rug under the dining room table and change the wall color back to white.

Agree with Nelly, its all about drawing your eye away from that half wall and to something else.

Thank you very much for your comments and suggestions!

This half wall is really an eyesore but one that I have to live with for now.

The light fixture idea is great as it is something that can easily be done without any structural changes. I will definitely replace it with something more stylish. The navy paint color in the dining room is also easy to revert back to white.

For the half wall, should I maybe just leave it plain white, without any art or decor? Do you guys think that would make more sense visually since the main goal is to make it “disappear“?

Put in the new light fixture and then take another look. A piece of interesting art behind the sofa would also draw the eye away from the half wall along with a nice light fixture. Definitely not the baskets on that wall, they really draw the eye there.

Any option for you to remove the walls and open the rooms up?
