I painted the nursery, but not a "baby" color. I painted it a nice medium grey, and I love it. But that's just me - I hate "babyish" nurseries.
This. We are painting the room gray. I am not in to "themes" in nurseries. I want the room to be able to grow with the child so we really just chose a color scheme and are going with it. I will say our daughters room is a really soft pinky/coral which sounds awful when I describe it but it is definitely not babyish.
I agree about "babyish" nurseries.
We left the walls their original color, a light tan. We decorated by hanging some animal prints on the walls and using blue green storage baskets and a blue rug, appropriate for an older kid too, so we won't have to redo it when he gets older.
