I did this once before, but here it is another way. Gray is your base because that's what your furniture is. You need to add "something" to it...THROW PILLOWS! Of course! In this case, they carry every color under the sun! And they are the only color in the whole room except for the tiny flick of orange in the area rug and the green plants, which are minimal. Everything is black, white or gray. No, this is not shades of gray or any variation of such. This is Home Dec 101, as in basic decorating concepts. When you are working with the basic (gray), you can do wonderful things with it all by itself, and then at some point it needs something more to lift it out of neutral.
