Personal color cues enhance neutral living room decor by adding subtle personality and warmth without overwhelming calm base palettes. Incorporate small accents such as throw pillows, art prints, or planters in soft natural or accent hues inspired by your travels or nature. For example, a single large bold art piece can anchor a room and suggest your story. These accents create emotional connections and reflect your style, transforming a neutral room from sterile to lived-in. Start with a color you love and introduce it thoughtfully through textiles or decorative objects, maintaining balance and intentionality.
