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.
