When you see the White Heron on the same plain compared to other white colors it's easier to make a decision.

When

Beverly’s post is super helpful. I would check out BM Decorator’s White. Supposedly it’s a “decorator’s favorite” for being the right white for many houses.

I would look at White Duck next. Personally I dislike BM Decorator's White. It also has a much higher LRV than what you're looking for.

You do realize that if you use one color throughout a house, it is going to look quite different in different rooms. You are going to love it in some rooms and not so much in others. I would try a real room and not just a hallway, before I gave up on the color that a designer and a consultant recommended (hopefully they did it in your actual space!).

Sorry I do not think white is the answer for many spaces and IMO beige in any shade is not a neutral. Everything in the space affects the color of the walls so of course that same color looks different in different space . This is my fave cut 50% a soft hint of a neutral that goes with everything and seems to work in every space I have even used it in.It almost appears white in some . I have never thought about the LVR of a color when choosing paint for any client , IMO it looks good it works nothing complicated about it . I use poster boards I do not test on the walls so able to move the boards around in every space too. Lighting is a huge issue when choosing paint so make sure thta is the same in all the spaces . I happen to like LED 4000K everywhere but you choose what you like but remember it has an effect .
