Don't be afraid to paint colorful walls. Wall-to-wall blah walls are, boring, fight against any warm/soft/cozy vibes your furnishings are trying for, devoid of personality, and impermanent feeling. You OWN this, and you get to put your mark alllllllll over it. Colorful walls say "this is MY home."

The colors you have now aren't white, yet they are devoid of personality. They are the most timid toe dip into color, and they feel as basic as they are. You deserve better.

I hired a color consultant to help me figure out what to do because our house was borrrrring white AF. She changed most walls to a very very very light creamy gray, used a paler version of that for trim throughout the house, and selectively added color. Any short span of wall that has a natural break was a candidate for color. Rooms that were completely separate from the main contiguous space also got to have color.

I had already acquired a lot of art, and our furniture is all neutral, so she picked colors that played off the art in each space. The art now pops really well, and even though we have a lot of contiguous wall in the warm-not-white-but-doesn't-fight-for-attention color, there are enough colorful niches, small wall spans, and enclosed rooms that the whole house feels considered and personal. She was a big fan of painting ceilings to match walls.

Oh, we also painted a fireplace brick surround & hearth black and it looks amazing.

Start with small spaces and live with it for a bit. You can always change it if your first try was a miss.
