We all insist on choosing a bedroom shade from the little card, when it’s this one figure printed on the tin that decides how bright the room looks after sunset
Forget those pretty color cards—the tiny number on the back of your paint tin reveals the truth about how a color will actually look once the lights go down. Light Reflectance Value (LRV) is the science behind why your carefully chosen bedroom shade transforms after dark, and understanding it could save you from repainting.
