I frankly think that valances and especially doilies are really no longer seen nowadays. I don't think the white valance is too noticeable if you have your heart set on it. The pillow looks fine, and it doesn't have to exactly match the throw. Introducing some yellow or gold into the room might be a good counterpoint against the green and white. Do you have to buy all the furniture pieces for the bedroom? It's not really considered desirable to have everything in one style or color, it's too matchy matchy. It will be interesting to see how your white bedding goes with the alabaster furniture.

I know you two love it today. Take a tip from an old lady…don’t buy a set of anything. Pick some of the pieces (not the headboard). Let’s say you go with the bureau and the bedside tables. Now you look for a bed…think about a different headboard and a different shaped mirror over the bureau. For example: this is one is leather…same color tone, but different texture: Then a wow color on the walls which works with the taupes and blacks:

Really that is nice but we actually need a lot more info. To start the best way to do a bedroom color scheme is to start with the bedding and the furniture. So post pics of both of those and pics of the space.

Navy would be my choice.
