Ha! I just exposed a brick wall in my house, what do I win?
I'm going to go against the grain here a little bit. A neutral background and style in your home can be a good backdrop that will accentuate any features that you might add that are more eccentric ( i.e. wall art or accessories like a lamp).
I actually prefer the light grey walls, I have lots of smart lights that mean I can bounce light off them and give rooms whatever mood I want anytime I want. The walls are just the canvas now. Don’t underestimate an rgb light pointed at a wall to make things really colorful without being overly bright, and nowadays relatively privacy-friendly Bluetooth lights are available down at hardware stores for cheap.
Bland? Maybe. But it looks neat, tidy and breezy. We went an almost blue shade of white and tbh we love it. Combine it with almost sandy looking floors and dark carpets and it looks modern, and yet relaxing.
I am super partial to an exposed brick wall though! Love a bit of 90’s style but that’d look shit in my 2010s style cheap cookie cutter build.
