LRV stands for Light Reflectance Value and measures the percentage of light a paint color reflects. Alabaster has a high LRV near eighty-two, meaning it is very light and reflective. When choosing trim colors, selecting one about fifteen to twenty LRV points darker helps create subtle contrast without overwhelming the space. This ensures trim stands out just enough against Alabaster walls for visual interest, while maintaining warmth and harmony. Understanding LRV helps avoid harsh clashes or trim that disappears against walls.
