Also the accessories you use in your kitchen impact things as well as backsplash and lighting

Thank you for the responds. The floor is going to be grayish color(laminate). The countertop is going to be a white/cream color. Backsplash is going to be white also. LoL The house is still getting built, but I will take a picture of the model home and post it here.

Here's the model home picture. Our kitchen is going to be exactly the same except the walls are white.

a white kitchen with white walls is becoming more and more common nowadays. Don't forget you still have lots of other areas where you can introduce colour (flooring, countertop, backsplash, kitchen accessories and small appliances) to make the kitchen come to life.

See if you can have no staggered height cabinets and i would see if a proper hood fan is possible too

Patricia, why are you not for staggered height upper cabinets? I think it makes the room more interesting.

I think white walls would be okay with white cabinets just don't go with a really light counter top. Although a light cream color would look nice too like in the picture below.

If you go with white everything it would end up looking like this:

All white is very doable provided your lighting is good.
