Can you post some photos and more details?

I am taking away the picture in the 2nd photo and replacing it with 3 portrait pictures, and I want to put a large brass mirror over the fireplace. Please ignore the baby fire guard!

Another suggestion is Dulux Egyptian Cotton. I had it in my bedroom and it does have slight pink undertones so maybe worth getting a sample pot. It is quite similar to Skimming Stone. I suggest you paint your samples onto A4 cards and try them on different walls in the room stuck with some blue tack. I was advised to do this and it really helps. It works better than lots of paint samples on a wall which can be confusing. Purbeck Stone is a lovely taupe. This is Egyptian Cotton.

White or an off white. A very pale pink may also go.
