How It Works

LRV (Light Reflectance Value) measures how much light a color reflects on a 0-100 scale (0 = pure black, 100 = pure white). For wall/trim contrast, aim for at least 25 LRV points difference. Most white trims are LRV 82-90. Accent walls should differ by at least 20 LRV points from adjacent walls. LRV is printed on most paint swatches.
