Purchase bedding that features a print containing both aqua and brown. Look for a bedspread that has swirls of brown and aqua, for example, to tie the two hues together on the dominant space within your bedroom, which is the bed itself. Add some throw pillows in solid aqua and solid brown to create pops of each color on the bed.
Paint walls in the room aqua and brown. Paint the dominant wall a bold aqua and the secondary ones brown, or create color blocking on the walls, mixing the two hues on each wall in a geometric display.
Carry the hues down to the floor with a rug featuring one or both of the colors. Place a small brown rug in one section of the floor and an aqua one in another, adding plushness to the floor and tying the space together.
Toss in glossy aqua accents to create a modern feel. Use a ceramic lamp, jewelry box or vase featuring an aqua hue and glossy texture. If you can’t find decorative pieces that are already aqua, purchase unfinished wood ones and spray paint them with an aqua paint that has a glossy finish to craft your own room additions.
Add aqua wall art to brown walls and brown artwork to aqua walls. Purchase and hang artwork featuring these hues, or create your own, having your teen help you paint shapes in aqua and brown on canvases.
Hang a cork board covered in a brown and aqua print fabric. Take a standard cork board and stretch the fabric across it, stapling it around the perimeter.
Use slip covers to give borrowed furnishings an aqua or brown hue. Many parents populate their teens’ rooms with borrowed pieces, such as recliners that once sat in a living room or a sofa that once filled a den. If that's the case in your home, use an aqua or brown slip cover to make the piece fit with the rest of the room. Toss on some throw pillows featuring aqua and brown prints to make the borrowed seating even more inviting.
