Hallways are often a difficult part of the home to decorate, and choosing a colour to paint a narrow hallway is even trickier. A narrow hallway can look very dark and tunnel-like without the right decor. You can use paint and other decorating tricks to make your hallway appear larger and lighter, even if it has no windows. With the right colour and a few other ideas to open up the space, your hallway will go from dark tunnel to cheerful passageway.Your first thought might be to paint the hallway white, but a hallway that is narrow, especially if it is long, will look sterile and institutional as a long stretch of white. A better choice of neutral is a creamy ecru, a very soft tan, or a sandy light brown. These warm neutrals give the appearance of a more open space, without the cold feel of pure white. Neutrals will complement the colors of any rooms opening onto the hallway, keeping your home harmonized.
Pastels with a warm base will visually open your hallway and are an excellent choice if rooms opening onto the hall are painted in similar colours. Your narrow hallway will open up and take on a welcoming style in a pale blue, soft pastel green, buttery yellow or the palest rose pink. Be sure to choose pastel colours with a warm undertone, as cool colours will give a narrow hallway a cold, dark appearance.
Paint baseboards and other trim the same colour as your walls, but in a semi-gloss finish. If you prefer to have the trim different from the walls, stick with the same color, but in a lighter shade. By keeping the trim the same or very similar to the walls, the hallway appears to open up. Avoid a tunnel-like feeling by painting the ceiling a lighter tint of the colour on the walls. You can break up the appearance of a long hallway and add interest by painting doors a bright, bold colour that matches the room they open into.
