A grey day is dreary and cool and can put you into a bit of a funk. So why would you want to bring that drizzly, damp color into your home? Because it can actually be a beautiful and seductive neutral. After all, it's no mistake that the hit book-turned-film 50 Shades of Grey uses the color right there in its title. There are so many different shades and textures that can really bring grey to life, letting an interior feel like a soft, comfortable embrace.
