A unified color scheme has a powerful effect on how expansive a room appears. Light, neutral tones such as soft whites, pale greys, and beiges reflect light and make the surroundings feel larger. For added interest, consider subtle color variations or accent pieces within the same palette, which can add personality without breaking up visual flow. Using similar colors on walls, furniture, and decor helps blur boundaries between spaces, promoting a harmonious, uncluttered appearance. By embracing cohesive color strategies, you not only create a serene backdrop but also maximize perceived spaciousness.
