Paint three of the walls a neutral color, such as white, cream, gray or beige, and use the fourth for an accent wall. Select a patterned wallpaper featuring touches of dark teal and one or two other colors from your color scheme. Or you have the option of painting all the walls a neutral shade and leaving the dark teal accent to be incorporated in other ways in the room.
Include one small piece of furniture that is dark teal, such as an arm chair, cabinet, end table or ottoman.
Incorporate the dark teal color in the room through your textiles, such as a dark teal, chocolate brown and cream rug featuring circles for a trendy teenager's bedroom. Dark teal satin sheets can work in a romantic bedroom, while teal chair slipcovers or place mats can accent a dining room. Choose curtains and throw pillows containing the color for an easy way to add dark teal accents throughout a room.
Hang artwork that features the dark teal accent color. Use teal frames or choose pictures that include the shade.
Accessorize the room with a few small dark teal accents, such as a glass vase, lamp or figurine. Too many dark teal objects can become overwhelming, rather than providing a pleasing accent.
