What accent color should I paint my end wall?

...you can't go wrong with a beige-y color... especially if the wall is large. A light wall color with darker furniture will look great and make the furniture POP!

If you want to add midnight blue pillows and decorator items I would suggest midnight blue on your accent wall. If you feel that is too much blue paint it the same grey as your couch and dry brush in metallic silver or white. Go easy on the metallic. Paint and feather it -not too much. Let it dry look at it and decide if you need to add more. If you think you got to much try feathering grey over some of the metallic. Add some mercury silver accents and sparkly pillows. Pretty!

I think I would go for a medium to light blue. Go to you're paint store and get a bunch of sample cards. Tape them to your wall. Go into the room at different times of day and in different kinds of weather. Take notice of the colors and eliminate them until you have a couple. Buy sample pints of those colors and paint them on the wall. Then do the same as you did with the sample cards.

I would stick with a lighter grey with tints of blue.

Hello! Grey walls are trending right now. I would do light grey on the wall. Hopefully, your grey couch is more toward a medium grey. That and a midnight blue chair will look great against the light grey wall! Good luck!

Shore grandson has nailed it. I would go with a light blue gray

I would go with lighter grays and then use cushions/art work/accessories to tie it all together.

I would go with a grey that is a little lighter than your sofa. OR.... go all out and do something different. Light rosy pink goes great with grey and blue.

How about a really light blue?

You are welcome! Gonna look great!
