I am not a pro and I am struggling myself with finding appropriate color palette, so take my advice with caution :)

You have a very nice space with many great thins (like that beautiful rug!), but to me it looks a bit to good put together, i.e. too matchy, so it feels a bit flat.

If you decide to remove drapes and darker pillows, you are left with the brown & beige furniture witch is pretty neutral and you can build up from there in many directions.
One possible color scheme in that case is brown/beige - blue - with yellow or orange accents. That is great color palette because blue cools down brown and space feels much more balanced in temperature.

I like the blue teal and golden yellow vase on your coffee table and would work with those two colors. Nice space! Best wishes!

I love the colors you have now, and the overall look of the room but (to me) it seems a little sterile. I look in that room and I have no idea who you are, what your life experiences have been, what excites you. Are there accessories and art you could add that would personalize the space a little?

I'm thinking maybe an area rug might be a nice way to add some accent color.

Please send inspirations I would appreciate it

Start by replacing that dinky thing over the sofa with art, then use that to inform the colors in the room. Here are two iterations, keeping some of the rust:

I like the arrangement Nancy suggested. It looks as if the sectional is blocking the entrance to the room.

Why are there twelve pillows? Is there no back support? Where do you put them all when people sit down? The blue from the vase & chair might be nice to continue.

I like Grover's last PS a lot!

I have no suggestions but wanted to comment that I LOVE Grovers mock ups!! They really help to visualize what can be :-)

Me too, Grover is great at it. The blue would work fine but in a brighter tone as that's what gives the personality to a room. One more color would help too. For me, art work is the frosting on the cake, the minute it's hung the room sings.

I like Grover's with the lime green pillow.

I was thinking the same thing, Finally! Really great idea. Green brings life everywhere, and would be a nice surprise in the room. Blue is typically a go too, but in this instance, seems 'expected'. The green with the art highlight, is very nice.

I think art over the sectional would be a nice addition. I also raised the drapery panels at the windows & matched them to the pillows.

I would pull colors from the chair. The blue is nice. I would stay away from colors that are too clean (use more muted) because the other colors are earthy. Pretty room.

Beverly's art is here. This is the enormous version, but if you follow the "More info" link below the photo, you should be able to find it in a smaller size.

Here's a link to the canvas in smaller sizes. https://www.art.com/products/p29373532655-sa-i8688526/avery-tillmon-pencil-floral-ii.htm?upi=PXZF3RO1ZLN&PODConfigID=4985770

I'm guessing you'd need 30 x 40". Please note that the pre-framed version is actually cheaper. Also, art.com is always running sales, so I'd keep an eye on it (or anything else you choose there) and wait a bit to see if you can't get 50% off.

Canvas, framed prints have glass over them and they reflect too much glare.
