Is it imperative you keep the dark wood ? I actually do not like it with both the light wood furniture and the style of the furniture BTW naew cahndelier hug lower and with the lights lighting the table not the ceiling would be a better choice with that furniture.What are all the chairs doing inthe space and from what I see they are pretty MCM so I think the dark wood needs to go.

Unfortunately my husband likes the wood. iIt stays. The chairs are just nor put away. At this point we can only paint for now.

a sage green would help minimize the severe contrast.

Yes, sage green, but lighter than the border of your rug. Also plan to replace the rug with something lighter in color and use very light color fabrics for the runner on the buffet and one on the table. Also, the centerpiece on the table should be white or off-white. I'd also put something white or ivory on the buffet (candelsticks and/or a vase with white flowers.)

Lower the chandelier to 30" above the table. Find a great new rug and pick your color from it. If you can't replace the rug, use your favorite color in it but several shades lighter on the walls.

Pick a light color with rug, like sage or olive or "Snowbound" paint color. & ceilng a satin.

I love the wainscotting as is. To me it is the furniture style that is not fitting in.

I tried a dark green,

Thanks, all all! Looking at sages that complement BM cushing green HC-124 which is on cabinets around the corner. Any recommendations for sages?
