Using high Light Reflectance Value (LRV) paint colors like warm whites or soft neutrals brightens and modernizes 80s homes effectively. Pair these with layered lighting—combining ambient, accent, and task lighting at warm color temperatures—to create a cozy but luminous atmosphere. Avoid harsh, cool lighting which can make spaces feel cold. Incorporate glass elements and reflective surfaces to bounce natural light throughout. Together, these paint and lighting strategies open up rooms while preserving a welcoming, modern vibe.
