Moving into a new home and will be painting before we move it. The floors are on a darker side throughout home. How do I decide on paint colors? Does the whole house get the same color? The first floor is foyer, dining room, kitchen, den, living room, and formal living room. I like gray walls - would I stick to that in every room? Darker in some? Any and all suggestions welcome. Here are some pics for context (not my furniture).
