Using a neutral, light gray for the walls, build your room around a modern and sleek look. A light wood for the floor, such as pine, blends well with an off-white color for the molding and door frames. Furnishings with simple lines and curves keep the room from looking too full. Fabrics for a modern scheme could range from solid, bold colors or geometric or striped patterns in a monochromatic palette to a pure white.
Using a gray for the walls that lends itself to some bluish hues will be complemented by deeper neutrals like browns. For a bedroom, a wrought iron bed with a brown cover and white accents works with gray. For a living room, a plush couch and love seat in a brown shade topped with blue pillows and white throw blanket creates an inviting area. Use gray-shaded wicker baskets to hold books and darker woods for shelving and tables.
A gray room benefits from pops of color. Red is an energetic color, and when used sparingly in an otherwise neutral room, the end result is invigorating and appealing. With a dark gray wall and white molding, a couch in white with accents of red pillows brings life to the space. The idea is to keep your main pieces solid and in white, gray or black with the accent in red. Incorporate solid red, stripes with red, and elegant paisley patterns with bits of red in your pillows and the upholstery of other furniture. Use dark woods in your other furnishings for this look.
Light shades of pink are pleasing to the eye and promote relaxation. With a gray color scheme on the walls of a baby girl's room, use splashes of very light pinks on the moldings and door frames. A rug in a soft pink and brown pattern or a solid of either pulls the room together. Furnishings in a light wood or white complement these colors. For a baby boy's room, use a light gray on the walls and incorporate darker grays into the furniture. Use a very pale blue that is almost white on the moldings of the room to accent the gray.
