But this weekend in KC I saw a pillow that was just what I was looking for. I snapped a picture of it for reference.
I used that when narrowing our colors. We are planning to do the walls in the lighter grey and use the green for the accents. The darker (smaller) green pictured matches the pillow a little better in person, but it seems a little dark in the room so I think we are leaning toward the lighter (bigger swatch) for the green. There will be "something green" on each side or wall of the room. A few of those things are: above the changing table will be a large frame, the end table by the glider, the curtain rod holding the black and white curtains and the knobs on the dresser. Potentially the frame around the map above the crib too, but we aren't sure about that.
And for fun here is a pic of me in a similar "green" color :) 21 weeks!!
