When working with whites I often just use the same white in a different sheen for the walls and trim.So matte for the walls and semigloss for the trim they look a bit different just becuase of the light hitting them. I do not like whites with yellow undertones and I also always make sure the lighting is all LED in 4000K before choosing colors.. With grays you also need to be careful working with anything but a pure white.

Thank you for your input. Unfortunately, we have to pick the paint color before lighting is in. We are also having to select wall color from out of state making it extra difficult. I am about ready to go back to one of my tried and true - Agreeable Gray or Repose Gray. If I select off white and should use the same color on trim then Alabaster would be the best option, I think Peary white will look off for the doors and trim in other areas of the house.

I know this is an old post but could anyone share a photo of pearly white in your home? I have very red wood floors and worry the yellow will pop and clash.
