How about finding some colorful toss pillows for the sofa and pick a color (or colors) from the pillow for the walls? Just be sure the tone of the paint will complement the floor and cabinets. You may even be able to do two different colors in the space(s). Here is a pillow thought. Stay away from the beige walls!

PS Find a complementary fabric for the dining chairs for a fresh update there too. These chairs are super easy to reupholster.

All I could think of is shades of firenze colors just like this.

I think if you choose colorful Roman Shades instead of the blinds it will add a lot to both rooms or if you like the blinds, put up some drapes with grommets with nice rods (you can get some really nice rods at Lowes.) Once you have window treatments you like and put up some artwork the walls won't look bland at all. In fact, I prefer antique white walls.
And do choose some artwork or photography for your space. It is so uplifting! Our minds need visual escapes at times. And choosing artwork or photography you love can be just that. Choose a waterfall, ocean scene, place you have been or dream to go!
I am with Darzy choose some other color elements prior to deciding on paint.

why not try tone on tone warm biege with some color in it. Each wall/ room area could be a separate beige color with accents of the other beiges as trim. I agree with adding color as accents in pillows , art and curtains.

Aaaah I've already made throw pillows to add extra color! I was thinking of making matching curtains. Too tacky or great idea? Curtains are so expensive!!

I love, love your throw pillows. I think making drapes out of that material would look sensational!

No beige, too 1990s. Go he great grays out now. Pewter Benjamin Moore. Edgewood gray you can mix it up for interest.

Add some bar stools in silver metal.

Add roman shade in black to window.

Throw pillows look traditional and your room looks contemporary with dining set and brush nickel lights etc. stay with that look use teals and turquoise as accent colors for pillows. Add roman shade to window by chair.

What great ideas!!! The builder says they didn't make a mistake BUT the bar is 47" high!! I cannot find stools anywhere! Should I @travisinteriors you think teal accents would go good with the green couches and dark cabinets? I think if I picked a different granite, the room wouldn't be so limited to the reds and greens...ugh!

Pale gray walls...would be beautiful......and my second counter is 44 inches..and I found stools online and they are pricey. type in ...Tall or High Bar stools.

Go with a sage green to coordinate with pillows. Had that color for 10 years, repainted with a more beige color and wasn't as happy. Sage is a great neutral, can use with many other colors. Doing black cabs in my new house, and sage swatches look great with them. Or, more of a yellow-green. Not beige, not gray!

You could get someone to cut the bar down to counter level, but would have to match granite (probably impossible) or coordinate. Or, replace that section of granite. Odd. Or, cut the bar lower and and add an interesting wood top, or other material. Friends did that, looked wonderful!

Did you decide on the color for your walls. Curious as I bought new home which have the same open plan and dark cherry cabinets.

@saradivi...no I have not! I'm going to put some samples on the walls soon though!
