This is new construction. First I will try to describe the space. Cabinets will be natural cherry, Shaker style with granite counter, either Jet Mist Black, or Black Mist matt finish or leather finish. Design generally is contemporary, rustic, Japanese features. Kitchen is open to the living room and dinning room, lots of windows, high ceilings with a clear story and exposed timber beams and natural cedar posts. Only 1 wall will have some upper cabinets along 42" and because I am pretty short, they will only be 15" above the counter. Most of the other two walls have large windows just above the counter by a few inches, interrupted only by a 36" stove and hood. My partner would like to fill the space between the counter and upper cabinets with the same Mist Black granite as the counter and use this as a backsplash behind the stove and between the windows. I am concerned that this will give a darkened appearance to the whole space, and will take away from a clean, contemporary look and weight down the whole look. Seeking advice about the effect of backsplash color, dark vs light on a space. The walls are white plaster, intentionally imperfect. I am attaching some photos of the space. The "cabinets"and sink in the photos are our temporary construction so we can begin to stay there while it is being finished.
