The best paint finish for a living room depends on personal preference and the desired look and feel of the room. Generally, a satin or eggshell finish is a popular choice for living rooms. Satin finish has a slightly glossy sheen that can add depth to the color and provide a more luxurious feel to the room. Eggshell finish is a low-sheen finish that provides a subtle glow to the paint color and hides imperfections in the wall. Both satin and eggshell finishes are also relatively easy to clean and maintain, making them practical choices for a high-traffic area like a living room. Flat or matte finish is also an option, but these finishes are more susceptible to showing imperfections and marks, and can be difficult to clean. High-gloss finish is less common in living rooms, as it can be too shiny and distracting. Ultimately, the best paint finish for a living room will depend on personal preference, the lighting in the room, and the desired look and feel.
