I agree that the wall color isn't doing justice to your space. How about getting the paint chip sample from your kitchen teal accent and get the lightest color from the chip to do the walls? It will guarantee the color will complement the kitchen. It would also enhance your floor and beautiful ceiling.

I did accent walls in my house. From vanilla white to a portobella beige, there is a huge gap. I even dared to choose a few really bright reds, before the final touch: contemporary paintings. My house today is like my masterpiece.

The undertone of your ceiling color does not match the undertone of your walls. Also the undertone of your floor does not match the walls. So definitely need to change the walls to something that works with both. A medium gray would be really pretty. Something in the family of SW Anew Gray or SW Amazing Gray maybe?

I would grab swatches to see what matches the undertones of your floor and ceiling.

@flo...your art is beautiful.
