Once you decide what color to go with, don’t forget about the finish. A high-glass coating can help a small space feel larger. To squeeze in extra storage, try adding little cabbies to fill in the space above a window or your range hood.
Keep everything by fridge, same color and it’ll feel more uniform. Instead of mounting your microwave on the wall, put it down below by your oven. That way, you’ll open up spaces for shelving. A glassy finish on cabinets also helps it bounces light back in to the room.
