The grey really makes the magenta POP! The color used about, of the time is grey, and the magenta is used about, of the time. This really gives the room a great color scheme and the perfect proportion of colors.
The room as a whole is too flea market for me, but I love that the room is colorful. I would not have color on everything, but one or two pieces is nice. I love the green doors on the wall as art - their color, texture and style appeal to me.
