I wouldn't choose the paint colour before the recessed lighting is installed.

What ingrid said....

Here’s a room with gray sofa and soft blue walls that looks very pretty

A couple more. Cream with a lot of cream and white accents.

You haven't said at all what other colors you like.

Although it is certainly easier to paint the less furniture you have in the room, it is hard to know what color to paint the walls when the only thing you have is the grey sectional and the television.

Will you buy chairs? Art work? Area rug? Cocktail table? What is your overall style?

They will have at least one other color, and when you know what your colors are, (light grey goes with so many many colors!) then you will be better able to pick put a wall color that will go with the colors of your furnishings and accessories.

generally you choose your rug, then your furnishings and curtains, they you get down to paint so you know it matches. You have your sectional whichis not what most would advise, but if you much keep we will work with it. Gray is a neutral color, so lets start with a rug.

under each pic is a button that says more info, if you follow that it will take to the site of the item giving price and sizes, i tend to be very reasonable so you should check them out. let me know what you do not like and i will toss them.

Hi Marie Clay-

Grey walls are quite the thing now but I am concerned that it is a trend that you may get tired of in a bit. If you are concerned about the dark floor, I would avoid dark walls, especially if the room doesn't get much natural light.

You could do a cool white with the tiniest hint of grey that really doesn't read as grey at all, or a very light grey that doesn't read as grey at all either.

Your room won't look too pale or cold because it will be warmed up by your art and accessories in the lovely accent color you have chosen of blue, green, and purple.

The paint companies have tools to visualize your room in the paint colors. Take photos of your room in the brightest natural light possible and have at it!

As far as a rug, think about your style, do you want an oriental rug, a soft floral or a modern style?

You can also get a simple jute or sisal rug, and leave the color to the art on the wall and punch up the color in the throw pillows.

You can look here for samples of the type of art you like, and you can see there are so many things, in so many colorways.

You might want to get some art for your walls first before getting a rug. You will look at your walls more than you look at the floor, and then you can get something more neutral and with less pattern for the floor if need be.

I think a greyed-purple or a purple with grey undertones would look fabulous with your dark floor and grey sectional. A bit lighter than your pillows. I'd just make sure to sort out the lighting before selecting the wall colour as it will affect how the colour reads.

marie, unfortunately none of my rugs have flowers as far as i can tell, can you give me a number? all would go fine with a light wall, generally i ignore the floor, you can not change it can you? so the rug is your new floor.

I too really like that blue and grey area one (the one from Wayfair, #4 the same one you like). You can then do accent pillows in either the light or dark blue or both. As far as paint, you can pick up one of the lighter colors in the rug. A color like BM Revere Pewter (a very popular color) would work well.

ok, i saved the one you said, please note it is blue and silver. it is also available in a few spots i think. some other things to go with the room
