Husband and I just started a new semi-custom build with a spec builder. They require us to pick all paint selections at the beginning of the project and I am so lost! We are to pick from Sherwin Williams and need to select interior walls (only get 2 options standard), trim, and cabinets. Unfortunately they won't allow us to paint the ceilings a different color than the walls, so I am leaning towards painting everything white. I figure it is much easier to paint walls than ceilings, so I don't mind adding color to our walls later on after we've moved in.

Now, which white to pick? I've scoured the internet and my top choices so far are (Sherwin Williams) pure white, eider white, snowbound, and alabaster. But, I'm having trouble visualizing these in my space. I'm afraid they will all pull too warm or too cool. I have used the Sherwin Williams Visualizer app but the colors don't seem terribly accurate there.

Our living area will face north and we will have windows on the north side of our kitchen as well. The living/kitchen areas are open to one another and have a light stain on the wood flooring. We will also have a car-side ceiling in the kitchen that I need to select the stain for. I was originally thinking of white-washing the car-side, but if I paint walls/trim white I'm not sure it will look good.

I'm including a stock photos from the builder's models to demonstrate our kitchen/living layout. Our countertops will most likely be some variation of white/gray marble or quartz (still picking those out). Our backsplash is Winterfrost marble tile laid in a herringbone pattern. I am thinking of doing the island cabinetry in "Anchors Aweigh" or "Naval" to add a pop of color.

Questions:

1. Which white would look better as an all over color? I think I would prefer to do a flat finish on the walls and then use the same color, but in a satin finish on the trim and/or cabinetry.

2. Would it be better to use a neutral gray (such as Agreeable Gray, Repose Gray (I would opt for 50% pigmentation) or even First Star on the walls and a bright white trim such as High Reflective White? I am worried about having gray ceilings.

3. Should I carry whatever cabinet color I select for the kitchen throughout the whole house (laundry room and bathrooms

Any help is much appreciated! Selecting paint colors before walls are even up is really hard!
