A light gray with a lavender tint to it, might go well with your white furniture and purple accessories. I have to agree about the tv, being way too high.

I just painted my Northeast facing LR Farrow & Ball Bone. In that light it is a very, very pale sage green. It might go nicely with your cream & purple

I think I would rearrange the furniture so the DR isn't blocked. Sofa in front of window & love seat in front of railing with the 2 chairs where the loveseat is now

Tv installation wasn’t my choice... I live with a MAN

Thanks for your ideas... keep them coming!

Select the rug before you select the wall paint or you will be repainting.

Your floral wall art might be a bit too "sweet' for this more contemporary room & it definitely too blue IMO.

This has warmth of wood, and some pretty purples....could go well with your brighter pillows..

I like that rug!!

Nice furniture and room. I suggest that you remove all the decor items e.g. vases of flowers, vases without flowers, plants in pots, pictures, pillows, artificial plant in the corner. Then take another series of pictures for us. For example, the fireplace would look better without anything on the hearth or mantle. Then take the (I think) video game stuff sitting on the mantle to the left of the TV, and put it in a box on the floor or hearth so it's more hidden.

Do you need to repaint? I think the current color looks good with your furniture and fireplace brick color. A rug will add a lot here. Are you happy with the arrangement of the furniture?

I agree with a room re-arrange. I live with a man too, so I feel your pain about tv placement. Maybe you could explain the Houzzer people are demanding you move the tv to the side of the fireplace. (It's been working at my house 😉 - the Houzzer power...).
Put chairs where sofa is and facing the window. The third chair....do you need it?

Great idea about removing all accessories... I didn’t really organize much before taking pictures... I can’t have a floor rug right now as I have an older dog who unfortunately has some messes.

The 3rd chair isn’t really necessary and I have buyers remorse but it was on sale and can’t return it... it will eventually go in a spare room but for now my adult kids are in those and there’s no other place for it😔

That's ok, you can work it in the room.
If you put your sofa against the railing, is there still enough room to angle the 3rd chair (as it will now be known) toward the furniture grouping?
P.S. I'm passionate about purple, so I'm loving your accent color.

Start with an area rug that you LOVE and let it guide the rest. consider painting the FP brick wall or trim color, and rearrange furniture so the sofa faces the focal wall. Keep us posted!!

Thanks, yes, I’d like to actually cover over the fireplace with the same type of painted mdf creamy wood with some tile around the opening and on the hearth

Sounds like a fireplace re-do might be a longer-term fix. In the meantime, I'd paint the mantle a dark brown, a similar colour to your end tables. It's not trim and shouldn't be white. It pops out too much in the white colour.

Another idea that doesn't involve any ripping-out is to go right over the existing mantle using a mantle slipcover in wood. Here's one of many how-to's on the internet. If you stained your brick as well, you could have a whole new look. https://www.fwmadebycarli.com/2011/01/making-of-slip-covered-mantel.html

My vote is not to cover brick. Contrasted with smooth leather, it adds texture, oh I wouldn't. Looks good with piano, dark tables... near the color of a chair...

a navy blue would look fantastic

purples and greens ?

those would look great to

I'd consider this type - delicate color you like with pillows [me too, btw]. Also the frame fits with dark chest, brick.... ? they sell larger -

Hi... the art I posted could be good next to fireplace, where a person sees most of the purple items [?].....

If you want blue art.... add a transitional pillow that has deeper blue in it / no rug to ground light colored furniture? and brick traditional as it is - room needs something with dark, with pattern I guess... ;)

BeverlyDez. had a good point about the room looking contemporary but floral arrangement is sweet and vintage-y [?]
