What is LRV and why does it matter? In short LRV = Light Reflectance Value, meaning how much light is the paint going to reflect 0 = black 100 = white It is important to know a paints LRV when selecting colors in your home: A paint with a high LRV will wash out with too much light which I why I won t recommend a high LRV color on the exterior of a home. On the contrary a color with a medium LRV below 60ish is going to present itself with a lot of depth on the exterior of a home When choosing whites and pairing colors this is also important: If you are looking for a bright and airy color you are going to want to get above 82 or 83. If you’re going for a completely moody vibe you will want to be below that 20 range
