Which color would look best in this living room?

Hello everyone! I just needed some advice on what color to paint the living room accent wall. I included a few other photos of the kitchen, doors, hallways, etc. so you can see the colors in the home. The paint in the living room, kitchen and hallways is Benjamin Moore – Thunder Cloud Gray (eggshell) and the accent wall is Benjamin Moore – Blue Note (matte).

I just worry if I get rid of the accent wall and make it all Thunder Cloud Gray that it will be too much gray (please ignore the white samples I painted). Any help would be greatly appreciated!
