Snowfall white from benjamin moore ( OC-118) is a great neutral white with a fitting name.. If you need something a bit warmer Navajo white (947) is a good one. We use Navajo White in my design center in our resource room in order to have as neutral and non-interfering backdrop as possible.. The best bet is to get a small sample of a few shades of white and paint them in swatches on the wall and view them throughout the day. With the changing light in the room - that will give you the best answer as to how they will look in your space.
