Many off-whites would work with Edgecomb Gray. White Dove, Simply White, Cloud White, Acadia White, Timid White, Swiss Coffee. You need to view them in your room with your light to make sure they work well together.

I used Simply White in my bedroom with Edgecomb Gray. But sampling in your room is the best advice. I have Simply White trim everywhere. What are you using for the trim color in other rooms?

Good point, kansdrespa

My niece used the following pallet for her home including Edgecomb Gray and White Heron.

We selected the trim color after picking wall colors and compared the trim that would be used throughout the home with the wall colors, her flooring and her kitchen and bathroom cabinets/countertops.

There were quite a few that worked with Edgecomb Gray, but none that worked as well with all of the other colors we were comparing as White Heron.

You need to test in your home no one can help with that part . Your lighting your stuff all have an effect on color I think since the wall color is decided maybe in this case do the walls first then test whites.
