My first inclination is also blue. Will you be painting just the walls in this sitting area or your entire space including your kitchen too? A wide variety of blues could work. You'd have to see what makes sense with what you already have in the room. Although a bedroom example, this shows how blue walls and blue fabric can coexist, and the brown, like your leather, works great with it.

I hate tile floors with a purple passion - however, they have their place. I lived with them in one house because I knew we were not going to be there long enough to get value out of changing them. When Katrina hit, water got into our second house even though it is more than 300 miles from the coast. That house had wall-to-wall carpet everywhere. We pulled up the carpet and replaced it with tile. I knew the tile could withstand getting wet, although it was unlikely to ever happen again. Plus, we loaned our house to friends and family from time to time. Even though none of them would ever abuse our house, accidents happen. With tile, I didn’t have to worry about the floor getting ruined. P.S. I have LVP in my closet (long story). I have most of it covered by a rug. I don’t like the sound of it. The round ”feature” in the ceiling is puzzling, not to mention limiting. From the photo, it looks applied, not an integral part of the ceiling. Is there a gap between the round thing and the ceiling itself? Wonder if you can find anyone else in the building who took one down and knows what it entails. Is there a building manager/maintenance person who has been there a long time? Maybe they know.

Do you intend to keep those mirrors on either side of the window? If so, then a round or circular light with texture makes more sense. But, if you remove the mirrors, the space will be more cohesive with a clean look, like the vibe of your living room, in which case I would do a linear light. I don't like for your space the linear light you selected, however.

We need more help to be specific. We can all see that your trim is creamy, but we need to know exactly how creamy it is and how dark it is. oncape is right that the easy answer is to use the same color on the walls, trim and ceiling. However, if you want other suggestions, not just the easy button, we will need you to find the closest match to one of the manufacturer colors (Benjamin Moore, Sherwin Williams, Behr . . . ) If you take a sample of the current color to a paint store they should be able to tell you the closest color in their brand to your color. It would also help if we knew the current color of the walls. They may be able to tell you the LAB or LCH values of the sample that they are color matching. They don't share the LAB or LCH values of their own colors. Another alternative that is not too expensive is to buy a color matching tool. These two are inexpensive and should be able to get you a close match to the colors you have: https://www.amazon.com/gp/aw/d/B0BGQMYJLS/?encoding=UTF8&pd_rd_plhdr=t&aaxitk=339657f6ddbd7c12d1e055c7e411ea30&hsa_cr_id=0&qid=1774962102&sr=1-1-9e67e56a-6f64-441f-a281-df67fc737124&ref=sbx_s_sparkle_sbtcd_asin_0rating&pd_rd_w=hPfvu&content-id=amzn1.sym.2fb72bc8-96ef-420d-b08f-c04b69f36507%3Aamzn1.sym.2fb72bc8-96ef-420d-b08f-c04b69f36507&pf_rd_p=2fb72bc8-96ef-420d-b08f-c04b69f36507&pf_rd_r=JQZCCMEBS6NH8SSJQE5M&pd_rd_wg=yY5ec&pd_rd_r=770e23a6-6773-44ea-ae5f-80ccdaf51234#customerReviews https://www.amazon.com/COLOR-MUSE-Portable-Matching-Scanner/dp/B0F8RH81LB/ref=sr_1_1_sspa?crid=19ASSYCW5ELQ6&dib=eyJ2IjoiMSJ9.mWd5oUGMRa8Tw438GQAeUN_3odv4OyMkk4OstO82RszKw5h5El7DStjkAfDY8CTp6_rEqf-xKFPzlxAC3eXlD1XsAEFa9iOnILBCi7pKteJKTTsEN4pITrL-Cx51zTN2UXYbh4pKfCqR-Y7UTwJHuy92MxZwFtUJTBZN61iCIiRy37Lcs0OymedMna1zvt2CVTEP8_ARF1uXMI1-pPDI4FlStj8oSQfDfqYq-rHhttg.88Qbx5WZeo9frKK9ZKXJYB-RENoYS0jjAPSgzXkE8_4&dib_tag=se&keywords=color%2Bmuse&qid=1774962102&sprefix=color%2Bmuse%2Caps%2C168&sr=8-1-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9hdGY&th=1 Kylie M Interiors also has some suggestions for colors that work with cream trim. https://www.kylieminteriors.ca/modern-paint-colors-to-update-cream-cabinets-trims-hail-marys/ https://www.kylieminteriors.ca/the-16-best-wall-colours-for-cream-cabinets-trim/
