The wall color is too much the same as the media center. Move the center pic down to be on the same line as the other two. Remove some of the photos from the center & replace with books. Things do not need to be symetrical just balanced to the eye. Include photos of the whole room so we can assist you better, please.

Historic interests?

Tan on all 4 walls?

More photos. :)

Without seeing sofa and other art -- I wonder about your blue on top OR bottom half of unit - kinda different idea? distressed... back of shelving.

New wall color. Need to see the rest of your furniture to suggest any color. Tan is always save, but will blend with your TV piece. Take everything of the shelves and move the items around, please add books, to get a new look.

I browsed and found distressed look. If all walls are the same and new-ish, you might not want to paint, but re-doing the unit wondering, like this or many others on houzz...

Someone suggested taking a lot out. What if you also removed some shelves and painted a color or two like this "paintbox" unit - place your 3 white mat items inside instead of above? Do you have white dishes or dining type? Simplify but put color where you need it: maybe so the white mats would pop off/ accented/ off blue, etc. paint colors on back of unit?

Media center too large and overpowering the whole room. I would get rid of it if possible and downsize....then choose new paint color.

For our OP, I like its size and that the surrounding area at tv "hides" it a bit. I suggested placing items above it inside the unit, in part to cut down the size.

A decent removable wallpaper placed in less of its shelves could be exciting. Nothing wrong with tan/ unless You hate it. Idea must come in other colors, but a red would be nice. blue too.
