I think that SW store could tell you which white has the same base colors as the agreeable grey. Paint companies usually have customer service numbers that will help with those questions. I think they do, too. Their number is 1 (800) 474-3794, I had a SW color consultant spend one hour in consultation at my house for $50 and then that amount was credited to the cost of paint. I don't know if the still offer this service.

What trim color did you end up going with? Do you have an after picture to share?

We used SW Creamy, it looks fabulous!!! I try to add a photo from my phone.
