The items you place directly on or around your purple couch will be the primary factor in tying this eye-catching piece of furniture to the rest of the room. If you want the scheme of the room to be different shades of plum, lighter or darker plum-colored throws and pillows on the couch will help set the theme. You can also set the couch up as a focal point by positioning neutrally colored items on or around the couch; creams, grays and even blacks can help highlight the sofa's color without overpowering the room with one shade. In the same manner, you can set the scene with other, contrasting colors, such as orange or green, by placing throws, pillows, rugs or other accent pieces in these colors near the sofa.
Unless your living room is the size of a small house, a dark sofa resting on a darkly colored carpet or wood floor can make the room seem monochromatic. With any non-neutral piece of furniture, it is often a good idea to position a neutral color directly underneath the item to help set it apart from the rest of the room.
One of the primary mistakes that people make when using color in a room is to attempt to use the same exact shade of the color everywhere. Unless you have several different items made from the same fabric, trying to mimic the same shade of plum in rugs, curtains, throws or other items will be next to impossible, and the resulting design can look messy. Purposefully using different shades of purple throughout the room that are the same tone but not the same shade as the couch will not only help your beautiful sofa stand out, but also provide your space with a cohesive look.
If you are like many people, your couch is probably not going to be the only seating option in the room. You can use furniture in varying shades of purple, seating made from the same plum fabric as your couch, or seating in contrasting colors. When opting for the latter, it can be a good idea to tie the different pieces together by placing plum-colored pillows or accent pieces on or near the contrasting seating option and placing accent pieces in the contrasting color directly onto the plum sofa.
