When metallic map value is lower than 235 RGB , the metal reflectance value in the base colour also needs to be lower. permanent watercolorsWeb27. dec 2024 · This number is on a scale between 0 (which is black) and 100 (which is white). A paint color’s LRV number tells you how light or darker it is compared to pure black (LRV – 0) and pure white (LRV – 100). In other words, a paint color’s LRV states its DEPTH (i.e. off-white/light/medium/dark). permanent water hardness
