Don't be so matchey matchey with pillows one black another with texture some print that calls you Magnolia market. Hobby lobby make your own So many creams and whites

I think I might get an area rug first, and then add pillows based on the rug you choose.

Lower your pictures.

I’m curious. Are your white couches leather? If so, how about NO throw pillows! Too slippery. But, if you really want them, how about limiting them to none on the chair, one on the short sofa and two on the long one. I agree that a rug will ground this space and suggest a color choice for the pillows.

I'd skip the pillows entirely, or get some more interesting ones, but my own priority would be a rug.

Select a rug first, then select colors from it for pillows....pull the furniture in closer together to complete a more refined look.

And use different shapes for more visual variety! I'd recover a few of the square guys, maybe compressing one to be smaller than the others. I'd make sure each couch had a ROUND one. Also consider the various rectangular shapes -- sometimes listed as "lumbar pillows." Good for chairs! And the cylindrical bolster-type pillows can be fun too!

Have you thought of pillow covers to change the look of your existing pillows. I have the same pillows, but the look changes from summer to winter and a few holidays with just covers.

Can anyone actually use that coffee table? It looks like it's plunked in the middle of a seating group where all the seats are too far away from it and each other to use it or converse. That chair in the corner is actually behind the loveseat. Is that where the naughty person has to sit?

Lower your art, pull the chairs up to the group, add a rug, then consider pillows.

See if you can find that blue in the wall painting or a lighter version of it that would compliment the painting and do consider other shapes -- at least one bolster pillow -- and, perhaps, at least one print rather than all solid colors -- something that reflects your personal taste and interest..

Art if I may comment, has such a presence that I can picture this type, but with 1 piece of art less? could look sharp.

Some kind of medium neutral could help.... Light colored furniture: on them, what kind of autumn leaf color have you liked [even experimenting with a blouse, a blanket]? On sofa try a softened or heathered-type autumn color, with yarns of grey/charcoal.

Hmmm.....and what about the black leather recliner? It's missing in groeraxle's delightful image above. Do you want to keep it in the room?

I LOVE what groveraxle did to make my room look different. I was wondering if everdebz could whip up a picture of my room with the more organic colours suggested?

I'd get smaller, lighter artwork along with your new pillows.

And yes, I sent the black recliner away because it didn't seem to fit.

Artwork stays since it is probably the most expensive and personal part of the room. That is what I really need to work around.

It looks like a new room with what Grover did in the last pic; beautiful! Not an art expert like Grover, but my first thought was that the art was too dark.

Some ideas

Lower the art and paint the walls a more neutral color to showcase the art and not compete with it.

Your current coffee table blocks the path into the room so a round table would work better in the space IMO.

So you wouldn't put a rug in that last one?

Sorry, Liliana, I posted my comment about the art before I saw yours. The second rug celerygirl posted looks sharp in the room, softens the darker elements in the room. Also like the wall color Beverly suggests.

Liliana I love your art, the wall color in Beverly's rendering shows it off beautifully!

Celerygirl, will you please post a link for that second rug?

We're not there to see sunlight shining in - and a small-ish room can't have that much going on - beautiful posts with rugs but for me, too much.... what about your photo without pillows, and maybe lamps too?

As much as I like Beverley's colour suggestion, I would have to repaint every single room in the entire house. I do plan to do that some day but my husband would divorce me if I suggested doing that now :)

I just want to stick to changing cushions, rug and maybe even the coffee table for now.

The photos I sent were on the dark side but the room itself I don't find that dark. We haven't had a good sunny day here for awhile.

Everdebz, I didn't really understand your last comments. Do you suggest no pillows?

I guess I am looking to focus attention on the art and the view, so I might consider a rug with texture, but maybe not too much color.

A coffee table with a good base is also an option.

That is very helpful! Can you do a pic with a Kilim style rug and different pillows, maybe in more earth tones or jewel tones?

Will your current coffee table base hold a round piece of glass?

Pillow covers with zippers. Advantage can change decor easily & wash.

How about reframing the art, perhaps in a light wood frame, then?

Your room has a lot going on - fancy arched windows, geometric lamp bases in a high contrast color against the wall, large art work. You sure don't need any more "pops of color" or anything like that.

I'd love to see a picture of your room without any pillows at all, and also without the smaller pieces of art on the walls and on the end tables. And without the red flower arrangement with twigs. Less is more here. The art work (hung lower and centered over the sofas) should be the center stage and there are a lot of things currently competing for attention.

After simplifying the visuals, then add a neutral colored rug with a bit of texture.

I'll bet there is some logical way to stop the paint color before it reaches the rest of the home. That gold is oppressive.

I love the sunny yellow walls. I have it throughout my house...Benjamin Moore Dance de Soleil. It makes me smile every time I look at it...especially if the sky is blue that day. I treat it as a neutral. Please don't change to the blah taupe. Reframe your pix in a light wood, lower them, put in a rug with blues and put pillows with blue tones and patterns, varied textures and shapes. I'm not much for modern but I rather like your coffee table. Perhaps moving your furniture away from the walls will help. It is a beautiful room. Enjoy it.

following

lepstein, apples and oranges to compare those two colors. Your paint doesn't have nearly all the black in the OP's wall paint.

The room needs a large interesting rug to tie all the furniture together.

Nice renderings Groveraxel & BeverlyFlaDeziner!

The rug images look great!

Hi, Lilianna. About the pillows. I would get 1 neutral color pillow & 1 pop of color from the art above. If it were me, I would choose a light blue that is in both the paintings for the pop of color.

I would remove the red pillows & flower arrangement out of the room. Put the black pillows on dark furniture or elsewhere to get people to look at the beautiful paintings 1st when they walk in the room.

I really like the art you have. Especially the one with the white trees. The black frames look fine to me. Changing the frame to a lighter color or reflective metal is an option,too. As for hanging heigth.

I also like the coffee table you have, however the one Beverly posted is nice as well.

The wall color is ok when light is in the room, but it does look "mustard like" in shadows or cloudy day. One day when hubby is up for it, a lighter subtle tone like others suggested will help. When choosing colors do samples in shadows, cloudy day, & bright sunny day to help the color look good everyday.

In the meanwhile is there anywhere a mirror could be put to help bounce sunlight around the room?

Just read your comment. I meant take a photo after removing items you might replace, and post it.

Great posts helped showcase your art better and created better balance: either without current table base...or less heavy/wide art frames. What do you think of those options?

Your initial photo bothers my eye cause the table base isn't in harmony with windows. Beverly's round one was good.
