Treat the brown walls as a neutral, and layer in furniture and accents in black and white. Move in a white desk with white bookcases. Roll a comfortable black desk chair into the area and hang art and a bulletin board with black frames. Black and white naturally create high contrast so emphasize the decor by placing black desk accessories on the desk. In this design option, brown is only on the walls and not brought into the room's decor.
Make the brown walls a part of the scheme by including brown accents. Place a black-and-brown-printed chair next to your desk for meetings. Anchor your desk with a cow hide rug, incorporating black, white and brown, on the floor. Frame a cork board with white molding and hang it over your black desk. In this option, black and brown are the main room colors and white acts as the accent color, brightening the room. Cover your books with brown paper and hang white drapes against the window. Use white desk accessories and place a white trash can on the floor.
Emphasize the accessories in the room by making them black. Since most computer monitors are black, surrounding the desk with black, especially if the desk is white, creates a lot of drama in your home office. Frame all pictures and organizational boards in black to draw your eye around the room. In this scheme, opt for wood blinds on windows for a modern look.
All-white accessories or all-black accessories are not the only options for black and white decorating. Black and white is such a popular color scheme that patterned floral desk accessories and black and white striped file boxes are available in the office section of most stores. In this option, the black and white accents are together and create a softer, feminine room when floral, and a masculine feel when striped. Bring brown in the decor by filling a black and white pencil cup with pencils and covering books with brown paper. Look for black and white draperies to complete the look.
