If you are sure that you want to paste wallpaper, I will recommend that it be blue. Because your walls and TV cabinet are white, and the sofa and coffee table are two colors.

Usually in a space. It is recommended to use no more than 3 colors for large color blocks. Of course, some small decorations can add other colors.

Or the main color is a color, and then it is good to draw a pattern.

You can take a look at the picture below, one is blue, but with some partition effects.

The other is a color block on which a pattern is drawn. Of course, it's up to you to make your own choice.

Sky blue, echoing the sofa, and at the same time, this color is good for protecting eyesight, just like looking at the blue sky.

The shade you use is cool, so... Purple bar.

Black and white, of course... Black and white TV retro...

Well, I imagine it. How about navy blue, it can be the same color as the sofa, and then add a little white pattern, which is the kind of small pattern with European style, which can be built with the wall, for your reference.
