So I had to put together some images so you all could see! Above would be the Warm Grey and Yellow on a navy blue wall. And below is the Warm Grey and Deep Blue combination on a yellow wall. The Warm Grey would probably show up best on a darker wall but we do have a Storm Grey color on hand that would work great on a pastel colored wall. The Storm Grey is about the same color as the Metallic Silver but without the metallic part.
Another awesome thing with these colors..... They are gender neutral! Go ahead and decorate that nursery before the baby arrives!
