I feel that too. My house had significant chunks painted a vivid aquamarine when I moved in 2018, and my now-ex insisted that we paint over it all in grey.
After she moved out, I put up greens, yellows, brown, and blue all over the house. It's not quite as "public pool" feeling as that original aquamarine, but it's certainly more lively than grey/white. Funny enough though, when I had a designer come in to take measurements and do a mockup for a kitchen reno... everything was back to white because that's step one in making it look "modern" even though part of the pitch is custom cabinetry that won't just look like that same white IKEA stuff that everyone installs now.
It's common for homes especially when prepped for sale because neutral colors won't clash with whatever the potential buyer might want to bring in e.g. furniture, artwork, or other decor.
Most of the rooms in my house are painted in colors and I mostly like it but it can sometimeds feel fatiguing. I've thought about repainting in a neutral gray or green.
Install the boring shit and use colored vinal wrap for fun. Good resale value and you can enjoy life.
