Green is opposite red on the color wheel. Therefore, green is the red sofa’s complementary color and will cause the sofa to stand out from the wall. However, it will equally make the wall stand out from the sofa. So, if you really want guests to notice your sofa, paint your living room green. Complementary colors in rooms are often used in modern decor styles. Yet the colors can appear harsh sometimes. Tone down the walls with a lighter hue of green. Also soften the harshness of two bold colors by including neutral colors in the room, such as gray, cream or off white.
Choosing an analogous, or related, color of the red sofa, such as orange or purple shades, will cause the red sofa to blend with the walls. These are the two colors right next to red on the color wheel. This type of color scheme can be as easy to create as the monochromatic color scheme, but it creates a richer quality to the room’s décor. Limit the room’s décor to three to five colors, as too many colors or hues can ruin the synchronization of the room. Perhaps you would choose a light violet hue for the walls, with your red sofa, and orange accessories. This would definitely give a room a modern color scheme.
Monochromatics are shades of the same color. Pink painted walls would be monochromatic with the red sofa, as pink is a lighter hue of red. The effect would be a blended color scheme, even more so than with analogous colors. This combination of colors appears simple and visually appealing but will lack some contrast. If you choose a monochromatic color scheme for the wall color and the red sofa, use a complementary color or an analogous color in other areas of the room to provide contrast.
Consider the effect of the living room paint color in relation to how it will make the room feel, in addition to how it affects the red sofa. You may be tempted to stay with a white paint, for simplicity's sake. But white walls can make a room feel stark and cold. An off white or cream would add a bit of warmth. Hues of purple or violet are considered warm or cool. When teamed up with a red sofa, which is a warm color, they would offer a warm appearance. A dark green on the walls could give the room an overpowering feel. A lighter fresh green could make the area feel full of life and offer a sharp contrast. Pink walls, with the red sofa, will offer a feminine or romantic feel to the room.
