No accent walls; you need rugs...BIG rugs. And art on the walls.

I agree. No accent walls. You can add molding. Wainscoting. Art. Lighting. Baseboards....

We’ll definitely be hanging art once I have an idea of the general direction of the accent colors. Any suggestions on what colors for rugs or art might work with what I currently have?

An accent wall might be fine, but it will depend. Don't settle on gray! That color may well depress rather than accent.

Yes, some good rugs will help.

No accent wall. How about rugs and art!

I agree with the consensus of no accent wall.

Art should be what you LOVE. Art does not have to "match" the room. So you can have a 6 foot long hot pink afghan on your orange and blue sofa if you love the afghan (maybe because your grandmother made it for you!). The afghan doesn't have to go with anything else because you love it and it brings you joy.

On the other hand, decor is just stuff in the room because it goes with everything else in the room. So your grandmother's afghan would only be decor in my house, even though it is art in yours.

And yes, I made the colors crazy just to illustrate the idea.

Select your art. Select a rug you love. Everything else will fall in place!

With all due respect, if you didn’t want blah, why did you paint gray? You need color: Pillows, rugs, art, cozy throws, table centerpiece, etc. I’m fond of clear true red. Punches of red would jazz up your room.

Pretty fireplace.

I also agree, no accent wall, but, if you really want to have one, then put it on the tv wall. NOT two walls. And pick a color, not gray. Color is what you need, in rugs and art and accessories, and pillows.

I appreciate everyone’s input! I get the strong impression that accent walls aren’t necessary, and that I should concentrate instead on getting my wall and floor decor in order. Thank you again!
