I would paint the entire fireplace including the mantel, all trim and shelving white. I like the Whisper White, but you must bring the paint samples into the room to see for yourself. The sheen on all woodwork should be semi-gloss, easy cleaning and looks crisp. I agree with painting the walls and I would paint the part above the mantel the same color as the walls, Summer Hue is beautiful, but once again I have no idea how that would look in your room. The walls should be flat most brands make a fairly easy to clean flat. If the fireplace were the focal point of the room, it could look very cool and dramatic to paint it a very dark gray almost black. But at least in this picture it seems that the entertainment/shelving unit is the focal point. hmm .... better stop while I am ahead.

Don't spend the money to match the exterior finish of the cabinetry on the cabinet interiors, you want the interiors to be easy to clean and a light material so you can see what is inside them. No one will notice or care if the interiors match the exterior (these days it is pretty much industry standard that they do not match) If the cabinet doors have glass fronts then definitely match the exterior or use a pop of paint color on the cabinet backs.

It took me ten years to figure out as an adult why my allergies are non stop when I visit my moms custom home. This morning I figured it out. Pine floors. We eliminated feathers, my seasonal allergies and there are no other triggers apparently in this house. I have to take the max allergy meds per day to be here. Treating the floor did not stop this from.happening to me as my allergies are severe. So heads up guys, people can react to the wood flooring even after its treated

that's what I meant. The cabinets below and above the counter can be finished with a light toned wood grained laminate. if you feel that is too plain, another option would be to go with light wood grain below and plain off white above. Maybe add a couple of wood grained shutters above also to break the monotony
