This is by far my favorite genre of design. I have a pinboard specifically dedicated to the topic, as I hope to always keep this mantra front and center in my mind while adjusting my own home.
For me, there's just something very sensory about layers of textures paired with neutral backdrops and surroundings. And since we get to work with pops of colors all day long, sometimes you want something to refrain from color. The textures then help the colorless things come alive.
