Hi Lynn! I've emailed dreamy whites to see if she can let us know the answer. It is a beautiful color!

Thank you for the email Becky,
The color of paint on the walls is called gray pearl.. It was a Martha Stewart color from Lowe's. They do not sell Martha Stewart colors anymore, but it should still be in their system. Also I used the Valspar Signature brand of paint.
Thank you,
Maria

I was able to sample Martha Stewart's Gray Pearl recently since Lowe's had it in the system; however, after sampling many white gray shades....recommend BM Paper White OC-55. Beautiful white gray.

Martha Stewart Gray Pearl color match using Valspar Signature, Satin, Formula: 101-13.5, 107-19, 109-1
