We can’t help you without some idea of what you WANT. Give us some direction. Do you want a new paint color? Wallpaper? Blinds? Shutters? A rug? Carpet?

New paint color maybe wallpaper, and a window treatment idea. It cannot be plantation due to the casement windows. No rug . This room faces north. I live in the mountains

So this looks to be your primary dining area, correct? My first impression is that it is dark and full of hard surfaces. Can you add a window on the large wall? That would bring in some light, but if not, then you need some artificial lighting, like a floor lamp, sconces, or perhaps a table lamp on a buffet. You could add a buffet on the large wall, with two skinny lamps on either end.

Why no rug? Rugs add softness and color/pattern to a room, as do curtains. I would add curtain panels on the window, mounted high and wide so they don't cover the glass.

First remove the clock and then get a nice chandelier that lights the space and the table ideally with LED bulbs in 4000K get a piece of art that is horiontal to hang above the wainscoting on the wall where the clock is. Take a colr from the art and do drapes on the window wall and BTW I hate plantation shutters so no problem there . I think the space is tight for a rug but a nice table runner could work for a bit more color.

Here are some possibilities to pull the entire visible space together since it opens onto the kitchen as well. The whole space is a mix of informal (kitchen, living room in distance with slipcovered sofa) and formal (dining room panelling and ornate pendant.) If you're only interested in making one change, skip my Comment. All my suggestions below take into account the kitchen and living room, all visible from the dining room to create harmony in all three areas:

--Repaint kitchen and dining room white to match your visible living area on the other side of the kitchen. As mentioned, your dining room and kitchen are dark--dark countertops, dark wall paint, dark floor, dark dining room furniture. Lighter wall paint throughout the entire visible space would give you a sense of flow and airiness.

--Remove that decor clock and replace with a beautiful, light colored horizontal landscape art work that will echo the outdoor view of your dining room window. A long, wide art work will give the feeling of another window. Art work can be abstract trees, skyscape, in greens, reds of falls, or whites as below. The creams and whites below echo your dining pendant. You could also do a pairing of two art works on that wall.

--Your pendant, though beautiful, seems far too formal for a dining area open to the kitchen and in a mountain house. But if you love it, then pair the ivory color with an art work and nubby linen ivory panels ceiling to at the window per Diana Bier. Also consider a new overhead light in the kitchen to upgrade that space since it's totally opening to the dining area.

--Consider adding ivory half slipcovers to dining chairs as shown below since you don't want a rug This will lighten the dining room and, again, echo your pendant and slipcovers at the other end of the space in the living room. (You could also paint the chairs ivory and your counter stools.)

Patricia is right - you need new lighting. Bringing in whiter light will brighten both the kitchen and dining room.

It appears that you have soft white lighting (2700k).

Changing the lighting will brighten you spaces.

You don't really want to pick your paint color until after you pick your lighting because the colors don't look the same under soft white lights as they will under daylight lights.

While getting your lighting think about the feeling you want for the room and the colors that you love and looking for that perfect piece of art that makes your heart sing.

A great piece of art can change the whole dynamic of the room.

I’d aim for light and airy by painting same as lower half or a slightly more creamy shade. Accessorize - botanical prints, a sideboard, black rod and drapes (IKEA has great linen like ones).
