In my opinion, a cuckoo clock is a very detailed design, but you say you want a simple design for the room. When you say simple, are you thinking of no wallpaper, no wainscoting, and no accent color on the walls? It seems as if dark orange is a color you favor. I see it in art images and in your curtain color. If this was my space, I would paint all the walls one or two shades lighter than the beige of the sofa to keep the room as bright as possible because the room has no direct sunlight. I would paint the ceiling 1/4 (one part wall color to three parts white). I would use a satin or eggshell paint instead of matte, semi-gloss, or high-gloss paint. I see some discoloration on the wall behind the sofa where the brown color of the sofa frame has worn off onto the wall. I suggest attaching bumper dots or strips on the wood frame of the sofa (similar to the ones used to keep cabinet doors from making a lot noise when they are closed quickly). I would consider painting the sides of the column with the cuckoo clock brown to match the clock. I would do this to call attention to the clock. I would remove the orange curtains and replace them with floor-to-ceiling length draperies hung as close to the ceiling as possible to make the room seem larger and taller. I would change the drapery color to match the walls, perhaps in a muslin-like fabric, which is a casual fabric. I always take my art to a professional framer. I have conservation matting and museum glass used for my art. I would have the three images you have rearranged as a collage in a very large single frame with medium to wide matting between the images. I would have the mat and frame color(s) enhance the images, even if it is a color I might never have thought of on my own. I would hang it above the sofa. I would use the orange drapery fabric to make throw pillows for the sofas. You did not attach a photo of the flooring in the room. A medium tone floor is easier to keep looking clean than a light floor/rug or a very dark floor/rug. Other "Houzzers" will give you completely different ideas. Use the ideas YOU like and enjoy your home!

I just tried a SW stain ( they can match it in paint) called Cape Cod Red that had a definite orange undertone and a burnt orange appearance when painted on our door. I thought it might be my eyes because the color didn't really resemble the chip or this photo. Then I spilled most of a gallon in the back seat of my truck and my husband and I agreed: Nope, it's orange. It might be worth a try. It was a pretty color without falling into halloween territory. Here's an ideabook showing some orange paints. https://www.houzz.com/magazine/dreaming-in-color-6-sensational-orange-bedrooms-stsetivw-vs~7014483

that's a lovely idea- the rooms do look cheerful- but i've read that orange can sometimes elevate the blood pressure- i've not really tried or experienced the effect of colors on moods- but m little skeptical because husband is quite stressed out most of the time so was worried if reds n blues would increase his blood pressure in anyway. thats why i had avoided those colors. green i'm already using in the bedroom- pink-i'm not a big fan of. so was thinking maybe purple/blue/lavender- would those be calming and cozy? i've not really color coordinated any of my rooms so far- this would be my first try and so i wanted it to turn out perfect.

Thank you Shalaka ! I do love it the way it is but since the windowstart are ceiling to floor and facing West, in summers it becomes a furnace. Hence the need for double curtains. So wanted to get something that when needed if I tie the front cream ones from the back when they show, it looks nice. While my husband liked orange, I was leaning towards, gold. So we decided to put it for vote. Thank you for your input :-)
