I don't see your walls as white at all. There is a nice contrast with your dining chairs and base trim. I would suggest enlivening the space with an area rug.

Benjamin Moore "London Fog" or "Himalayan Trek" are gorgeous neutral colors!

You have great taste!!! Can you take the picture from your front entrance and lean it against the wall in the dining room. It appears that it will work fine - you'd need to get something else like it.

I was also thinking art for that wall.

Some type of art for the wall

I think your wall color is perfect and your room looks beautiful and modern. I would take your time and find the perfect piece of art to add color to your space. You have the perfect backdrop for colorful/bold art. Personally, I don't think you need a rug under the table.

Love your very contemporary space snantel. Art is a very personal decision but we offer a range of contemporary collections from abstract to figurative which might like to browse. As others have already illustrated, a pop of colour would work very well against your neutral backdrop, as would keeping it more subtle. All down to your personal taste!
